cancuncaddy Posted April 12, 2011 Author Report Share Posted April 12, 2011 great news.........kinda... checked the connector and the diode as you stated ....thanks man!!! now im pissed off obviously at the alternator shop where the JUST FIXED THE ALTERNATOR. i pulled and replaced the alternator myself becouse the northstar spooked em! one of the mechanics thought it would be a neat trick to physically twist the diode ends together but real nice not just touchin TWISTED TOGETHER ABOUT 5 TURNS, I UNTWISTED IT AND PLUGGED IT IN AND VOILA!! A/C AN COOLING FANS .....BUT IM HOT AS HELL ! IM GOING RIGHT NOW TO RAISE CAIN AND SEE WHAT SATISFACTION I GET! THANKS AGAIN FOR THE COOL TIP!!! IF YOURE EVER IN CANCUN?

Cadillac Jim Posted April 14, 2011 Report Share Posted April 14, 2011 It's so simple to keep the sensors in place and no one knows at this late date what possible impact that a faux sensor may have. It's tempting in an old car to start disabling things. Some mechanics don't trust computers; you can tell by when they want to change a sensor or a module instead of looking for the problem that the code points to. I never let those guys touch my car. No car made since the 1994 model year will ever work right again if one of those guys has his way with it. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

cancuncaddy Posted April 14, 2011 Author Report Share Posted April 14, 2011 you guys are right -----but those particular sensors are a bit redundant and im in mexico and cant just go buy the parts i need! but i do try to do things right when i can" Link to comment Share on other sites More sharing options...
KHE Posted April 14, 2011 Report Share Posted April 14, 2011 Your A/C mechanic doesn't know what he's talking about. The thermistors DO regulate when the compressor comes on and turns off (cycles). They monitor the temperature of the refrigerant in the system before and after the orifice tube. The sensors are relatively inexpensive and many of the online parts houses will ship worldwide. I do not know why your local GM dealer can't get them for you - something is strange there.

BodybyFisher Posted April 14, 2011 Report Share Posted April 14, 2011 I gave you links to two on line parts places to get parts we have members all over the world who manage to get parts. What you did got it running but its wrong. I had to replace one of them because I put my orifice tube in backwards, and it was about $20 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...
cancuncaddy Posted April 14, 2011 Author Report Share Posted April 14, 2011 well i went to the gm parts place here in cancun and YES the part is in their computer but they say its discontinued and they cant order it.and if they could it would be 930.00 pesos for each one! and as far as worldwide shipping hmmmmm. autozone wont even send me something from mexico city much less worldwide! if you personally know of an autoparts place in america that ships reliably to mexico please send THAT link .thanks alot for all youre help and wisdom i really appreciate it!

Autozone is for slam-bang mechanics, that is not the type of parts place you should depend on. I realize that money is tight but you are driving a cadillac man. I have PREVIOUSLY given you two links in this thread, see post #28 in this thread TRY TRY TRY going to www.rockauto.com and www.gmotors.com if you go to www.gmotors.com you can fill out a request form and they will let you know the cost, tell them where you are located. As noted, www.rockauto.com ships worldwide. please stop making excuses, we are here to help but we prefer not to help or promote rube goldberg hatchet job remedies, we are here to help you do it right.

Cadillac Jim Posted April 14, 2011 Report Share Posted April 14, 2011 I'm not exactly sure what the part is, specifically since I never had a problem with my A/C other than the compressor shedding its reed valves at 85,000 miles or so, but I did find "Refrigerant Temperature Sensor" for a 1996 ETC on Rock Auto for $16.95, that looks like this: Shipping to Mexico can be steep from UPS or Fedex but it's not too bad if done by the Post Office. Two of them plus shipping should be less than the 980 Pesos == $83.55, according to XE.com, that those bandidos in Mexico City want for each one. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

cancuncaddy Posted April 16, 2011 Author Report Share Posted April 16, 2011 My bets are a short in the 2nd cooling fan attached to the radiator. disconnect the connector to the cooling fans & see if when the AC is put on it blows the fuse. The cooling fan motors are powered through the 50 A maxifuse labeled COOL FNS. The original poster is dealing with a 10 A fuse labeled AC COMP which protects the fan relays and AC compressor clutch circuits. nope turned out the diode on the compressor connector was twisted together my some malicious sob!
