coryno Posted August 31, 2016 Report Share Posted August 31, 2016 Thanks bodybyfisher and cadillac jim. I finally got the problem resolved but now im having another issue. My interior lights and cigarette lighter not working. I checked all the fuses and that was pretty much the extent of my troubleshooting. Do you have any other suggestions.

coryno Posted August 31, 2016 Report Share Posted August 31, 2016 It was the fuse that kept the fans from coming on which i most definatly checked first but must have blown afterward, didnt think of them again until i double checked every small thing before moving on to buying/repairing bigger problems. It doesnt overheat any more but there's spots on the ground where i park around where the center of the motor sits Quote Link to comment Share on other sites More sharing options...
Cadillac Jim Posted August 31, 2016 Report Share Posted August 31, 2016 Sounds like the inadvertent power is down. The two fuses to check are the 10 Amp MIRROR fuse and the 50 Amp INDVERT Maxifuse, both in the underhood fuse/relay block. The underhood fuse/relay block is under a plastic cover in front of the strut tower on the driver's side. There is a relay, the INADVERTENT POWER relay, also in the underhood fuse/relay block. I would wonder why a fuse blew, particularly the 50 Amp INDVERT Maxifuse. The Maxifuse replaces fusible links that were used to protect main or high power circuits in older cars and when one of those blows, there us usually a big short circuit somewhere. Now, how DID you solve that last problem, about the cooling fans and the long DTC list?

coryno Posted September 1, 2016 Report Share Posted September 1, 2016 (edited) It was the cool fns fuse that blew. I replaced it and the fans started working. Was there something else I was supposed to do from the list of codes in relationship to overheating. I also checked the battery it shows 12v on a multimeter. The fans switch on for about 30 seconds with the ac on and car cool and then goes off. Are they supposed to run continually Edited September 1, 2016 by coryno Quote Link to comment Share on other sites More sharing options...
Cadillac Jim Posted September 1, 2016 Report Share Posted September 1, 2016 Yes. when the A/C is ON, the fans should run on low speed continuously. How about a fresh list of OBD codes?

coryno Posted September 1, 2016 Report Share Posted September 1, 2016 I reset the codes and drove around the block to make sure the car still runs. I read somewhere that messing up these codes is costly and can only be fixed by a dealer.

That would explain the loss of interior lights and the cigar lighters. The rest of the codes are familiar from last time (I didn't check) but are all HISTORY, indicating that they are intermittent things. Some are puzzling, like the B1771, which shouldn't reappear unless you tried to play a casette. There are several Uxxxx codes, indicating that there is a problem with the car's network. The B2711 happens when the contacts to the chip in the key starts to go bad. Eventually you will not be able to start the car. Sometimes a new key is all it takes to fix it, sometimes the steering column needs to be taken apart and the contacts inside replaced. I would prioritize the problems and attack them one at a time.

coryno Posted September 1, 2016 Report Share Posted September 1, 2016 How do I troubleshoot the short in the interior lights and the car's network problem which sounds like it maybe a complicated fix? In regards to the key chip, the dash reads theft system problemb car may not restart, do you think that could be the cause for the B2711 Quote Link to comment Share on other sites More sharing options...
Cadillac Jim Posted September 1, 2016 Report Share Posted September 1, 2016 The B2711 tells you the problem detected by the car's theft prevention system. The message on the DIC is a result of that problem. I would start by getting a new key made either at the dealer or at an Ace Hardware that matches the chip resistance in your key. If that doesn't do it, you will need to look at the contacts in the ignition lock. You can troubleshot the interior lights problem by monitoring the B2472 code while you check fuses. First, try making sure that both fuses are good and see if the code goes to HISTORY. If so, and the fuses don't blow again, you are done. First, disconnect both CIG LTR 1 and CIG LTR 2 fuses and see if that fixes the problem, i.e. the B2472 code goes to HISTORY and doesn't go back to CURRENT over a day or two. If so, the problem is with one of the cigar lighter circuits, probably something in the cigar lighter itself, like a gum wrapper or a dime. If it is a cigar lighter, be sure that you find all of them. The Deville with center console (floor shift) has one there, under the radio, one in the front, and one in the rear in the center console, all on CIG LTR 1 fuse. Without the floor center console, it has one in the front, probably in the dashboard. The CIG LTR 2 fuse is for the cigar lighters in the rear doors. If it's not in the cigar lighters, close all the doors and see if the B2472 goes to CURRENT. If so, the short is in the courtesy lights. If not, check the vanity mirror lights first, then all the bulbs in the cabin. A short is probably a broken bulb. You really need a factory shop manual to get this car in shape and maintain it. I'm using the one that I bought when I originally bought my 1997 ETC in October 1997. You can get one on eBay at a reasonable price. I wouldn't worry about the network codes for now so long as they are HISTORY and the module involved is communicating with the rest of the car. Sometimes when modules are using the network a lot the message-passing clashes, like people talking over each other on the phone, and you get a network code that immediately goes to HISTORY. When you get the real problems worked out, then, if you have a persistent network code, we can look for that; it's usually a loose or bad connection (or broken wire) in the network circuit, which uses PPL wires.

Cadillac Jim Posted September 2, 2016 Report Share Posted September 2, 2016 OK. With the codes, we can zero in on fuses, relays, fans, or wiring.

Anna Flournoy Posted May 2, 2019 Report Share Posted May 2, 2019 Ok looks like last post was a handful of years ago, so hope to get a reply.. same deal was told the Dan motors are blown and need replacing, mind you I just purchased this car as is with this existing problem.. anyways seller said radiator was just replaced and they broke an account line when putting in a pump, but can't find the break in ac line haven't looked that hard either I actually accidently turned on the ac for the first time yesterday and was amazed it was cold continuesly so I don't know what the deal is there...but if the overheating has to do with the ac line maybe that's the issue but I highly doubt it.. for a quick fix I was going to just bypass the maxifus... ( A little background, got my 97 DeVille cheap, has issues but runs and is my home along with my boyfriend and service dog, being said cheap tricks or make do's work and are sometimes all I have to work with so please let me know the right way of course and any possible cheap temprary fixes (with temperary time limit if any...had a car catch fire cuz I didn't fix a temp fix and we'll 6onths after the temp fix done I drove out of state to the car catching fire in the desert..the temp fix wire was to small for the load it carried) ok enough with the babbling.. my codes (after I reset them) are attached.. ok don't want to attach so..

BodybyFisher Posted May 2, 2019 Report Share Posted May 2, 2019 @Anna Flournoy This is a little confusing PLEASE explain what your problem is. Your post is in a thread dedicated to a 97 HVAC FAN NOT WORKING, but if your AC is working that isnt true It looks like you should have an AC problem based on a mechanic statement but it works? You want to remove a MAXIFUSE why?, for what purpose? Is it overheating? We need you to be clear here for us to be helpful, thx Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
BodybyFisher Posted May 2, 2019 Report Share Posted May 2, 2019 P0603 is not a problem most likely the battery was disconnected These are your AC codes DTC B1340 Air Mix Door One Movement Fault DTC B1341 Air Mix Door Two Movement Fault DTC B1348 Very Low A/C Refrigerant Pressure You should have your AC system serviced. DO NOT try to charge it yourself. It needs evacuation which will also test for leaks (as a vacuum won't be possible to be pulled) leaks would need to be repaired if there are any. It will cost about $125 usually to charge an AC system, plus any repairs of components damaged by that 'mechanic'. You are also having problems with your air mix door, Ill need to look into that further. Your ABS and TC problem is caused by this DTC C1223 LR Wheel Speed Sensor Input Signal is 0 DTC C1224 RR Wheel Speed Sensor Input Signal is 0 DTC C1236 Low System Supply Voltage This is relatedly to steering and ABS DTC C1241 Variable Effort Steering Circuit Malfunction DTC C1243 BPMV Pump Motor Stalled DTC C1255 EBCM Internal Malfunction These problems are not easily fixed and require someone with diagnostic experience. You said they broke an ACCOUNT line replacing a pump, what pump? What do you mean by account, AC line? Was the line repaired? If this car is overheating, given its age and unknown history, the very first thing you should do is check to see if the head gasket is blown before investing anything in this car. Buy a Balkamp block tester from NAPA on line, it is $50, and it is where I would start. Then I would pressure test the system to see if it holds pressure, check that the cap holds its rated pressure, check the water pump belt and tensioner, make sure the air purge line is clear (I would do that first check that the air purge line is clear) and make sure the coolant concentration is at least 50/50. But please, explain what you mean in detail by 'overheating'.

Anna Flournoy Posted May 4, 2019 Report Share Posted May 4, 2019 Ok the car simply overheats I drive it to around 230 than pull over and wait until it cools down, while pulling over the most it has risen to is 243. I was told the overheating is because the fans need replacing (per big o tires, per previous owner) Quote Link to comment Share on other sites More sharing options...

Anna Flournoy Posted May 4, 2019 Report Share Posted May 4, 2019 Ok well fans I was told motors blown on the that's why they needed replacing confirmed with a me hand c friend of friend who glanced at car who agreed change fans out . Then when I was overheating on the fwy when I pulled overand poppedthehoodto my surprise one of the fans was spinning and like I said I pull over at 230° so if that's when they cone on I wouldn't have noticed previously and the low fans be don't seem to cone on that is why I was going to test by bypassing maxifus that operates the trigger of them and if they work then do a permanent bypass with a switch under dash to turn on and off.. Also u checked that last one sone gluid squirted out it was wet on both sides and no clue g apparent to me I then got a metal wire and purged each side about 6" with it one side did feel like it hit a wall of a line turn after that distance could that be clog?

BodybyFisher Posted May 5, 2019 Report Share Posted May 5, 2019 You made a mistake, you stuck that wire into the air purge orifice, NEVER do that, it will only recirculate back and clog again. If that was clogged, that could have been your overheating problem. But because you didnt remove it to inspect it you won't know for sure. Also, this is the reason NEVER to put the cooling system coolant tablets into the coolant tank, it will clog this orifice, they must be crushed and placed in the upper hose. Keep an eye on that orifice going forward, do not blow it out or stick anything in it. REMOVE IT with a 15mm box wrench and THEN clear it. Here is a test Start the engine, let it idle, turn on the AC Lift hood, look at 2 fans, are they turning?

Anna Flournoy Posted May 6, 2019 Report Share Posted May 6, 2019 Ok yeah I watched another video to discover I had the wrong line and it is just before the line I uad.. the avideo was showing how to bypass whatever from the part that comes out from engine compartment to part I took a picture of the.. anyways haven't had time yet to try and redo the clearing of that line.. confused a little on how to clear it now though that u said to use a 15mm box wrench... Is that different from a 15mm socket on the rachet (guessing similar but square not a hexagon) and then I actually remove where the hose attached on the spot closest to the radiator from picture I sent? And the lint just before the line I took off should I remove that one to and should I turn on the car with these off.. I'm sorry for the over questioning, I just want to be sure to do it right. As for fans with AC on I would say no, I checked them when I ran the ac for the first time after it looked as if one was on when I was overheating, and so wanted to check so put temp co trol as low as it would go and the fan mode on econ hi and they did not come on.

BodybyFisher Posted May 6, 2019 Report Share Posted May 6, 2019 I want to apologize, your writing style it too verbose, too meandering to follow. This is a give and take of extremely detailed information that must take place in order to solve complex problems. You keep speaking of easy fixes and bypasses which to me are the exact opposite of what should be done. These are complex cars and they need specific diagnostics not haphazard fixes. We need DEFINATIVE answers to diagnostic questions. You seem to be being led by some other source, which is confusing the issue. I PM'd you my mobile number call me, I believe we can walk through the issues faster and more focused. I said 15mm box wrench because it is more common than a 15mm DEEP SOCKET which is what you would need over the orifice nipple. @Anna Flournoy Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
