kenjobb Posted February 5, 2014 Report Share Posted February 5, 2014 So i just bought an 02 seville sls from a small private owned dealership in medina ny for $1450 and thought i was getting a steal. He informed me about the faulty overdrive sensor but not that the defrost and front blowers hardly work but the car will get warm. The front passenger and rear driver windows don't roll down from the driver controls. And now the abs and traction control lights keep popping up but go away for awhile when i turn off the car and back on again. I was super excited to get my first caddy and still kind of an because the body and interior is mint and the engine seems mechanically solid. I am somewhat car literate having going to school for auto body but the in depth mechanics escape me. How bad is it really and how much will this hurt the wallet?

KHE Posted February 6, 2014 Report Share Posted February 6, 2014 I'm not aware of an "overdrive sensor" in these cars. Was your muffler bearing and canoe-tin valves OK? With the key in the run position or the engine running (it makes no difference), simultaneously press and hold the ON/OFF and INFO UP buttons on the dash to the right of the speedometer and above the gearshift lever. The system will go through a segment check and then you will see ALL? on the driver information sensor (DIC). To operate the diagnostics, the following buttons are used: ON/OFF = Yes INFO RESET = No INFO UP/DN is the toggle to between systems To exit the diagnostics, repeatedly press the INFO RESET button or turn the ignition to OFF. Any codes will be displayed on the DIC as CURRENT or HISTORY. The window issue may just be a bad master switch assembly at the driver's door. As far as the transmission goes, I would not be surprised to find the PCM P0741 code either current or history. The codes will also point to the problem with the ABS and Traction Control lights. The blower issue may be a bad blower motor - it is much easier to replace the blower motor on the '98+ models of the Seville vs. the '93-'97 models.

Logan Posted February 6, 2014 Report Share Posted February 6, 2014 I think the 'overdrive sensor' issue refers to the famous TCC code. Maybe he'll get lucky and find a 1860 code too.

kenjobb Posted February 6, 2014 Author Report Share Posted February 6, 2014 My uncle is switching cars with me tonight to take it to his shop tomorrow to give full diagnostic and bumper to bumper look over. She will shift fine if i go easy but not if i punch it. Link to comment Share on other sites More sharing options...

KHE Posted February 7, 2014 Report Share Posted February 7, 2014 I didn't check the blinker fluid either LOL... Check the codes as I described in my earlier post and report them back here. The codes will tell a lot about what's wrong. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...

kenjobb Posted February 7, 2014 Author Report Share Posted February 7, 2014 Yea there was but I was just trying to get them written down in time. I know the first 4 C codes were abs codes. I'll have to go look again on my next smoke break Link to comment Share on other sites More sharing options...

Logan Posted February 7, 2014 Report Share Posted February 7, 2014 Actually...it's good news. You can forget about most of those codes. A code p1860 will cause a false PO741. A open TCC solenoid in the trans causes the P1860. It's much better to have a P1860 and PO741 code together...then have a PO741 code by itself. A PO741 code alone is major work deep inside the trans. That said, the pan on the side of the trans has to come off to replace the TCC solenoid. To get the side pan off, you have to drop the trans and engine assembly about 10-11 inches. There is a video on youtube about replacing the TCC solenoid with the trans in the car. That said...better have a plan B ready if you use the video.

KHE Posted February 7, 2014 Report Share Posted February 7, 2014 The torque converter solenoid (TCC) has failed. That is under the transmission side cover. You can lower the trans or remove it from the car and replace the TCC - a big job but not that bad. You got the car for a very good price most likely the seller was afraid that it needed a new transmission and torque converter.

Logan Posted February 8, 2014 Report Share Posted February 8, 2014 I think we are posting on top of each other... I think the P1860 is causing a false PO741.... I posted a pic of the bad solenoid....see yellow arrow. Note the engine/trans has been dropped about 10 inches to get the side cover off. It would be worth the time to check the large transmission wire harness connector.

kenjobb Posted February 8, 2014 Author Report Share Posted February 8, 2014 Ok cool. I have a couple mechanics in the family anyway. What about all the speed sensor shenanigans? Link to comment Share on other sites More sharing options...
Logan Posted February 8, 2014 Report Share Posted February 8, 2014 What?....the ABS codes? Maybe bad hub bearings or even unplugged.. Someone may have started to work on the car... I would leave the ABS alone for now.

Cadillac Jim Posted February 8, 2014 Report Share Posted February 8, 2014 Yeah, the wheel speed sensors are unplugged. I would begin with a thorough inspection, using the codes as a guide, looking for unplugged connectors and loose bolts. -- 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.

kenjobb Posted February 9, 2014 Author Report Share Posted February 9, 2014 Thanks a bunch guys, i was afraid the Wheels and tranny were gonna go flying in all directions haha. Where is the blower motor located and how hard is that to change? Link to comment Share on other sites More sharing options...
Cadillac Jim Posted February 9, 2014 Report Share Posted February 9, 2014 There are two blower motors for the 2002 STS, one with a detachable vent (output) tube that is re-used. Check the part number by VIN when you buy. The blower motor is under the dash on the passenger side. Spelunking experience is a plus when replacing it. The 2002 FSM gives this procedure for removing the blower motor. Remove the right side sound insulator (the cover above the foot room that covers the under-dash area). Pull back the carpet near the blower motor. Remove the glove compartment (see below for steps). Remove the DIM (dash integration module) from the bracket. Remove the two rear DIM bracket screws. Move the DIM bracket out of the way. Disconnect the wiring harness connector from the blower motor. If you have a detachable blower ventilation tube, pull it off at this point. Remove the three blower motor retaining screws for detachable tube, or four screws for non-detachable tube. Remove the blower motor. If you don't have the detachable tube, you will need to rotate the blower motor to remove it. Installation is the reverse of these steps. The glove compartment removal steps are: Open the glove compartment door. Remove the audio/visual (A/V) adapter from inside the glove compartment. Remove the glove compartment lamp. Lift the glove compartment door just a bit and slightly twist the rod that holds it from opening too far about 1/4 turn to disengage it from the door. Remove the screws holding the compartment cavity to the dashboard. I think there are four. Work the compartment cavity partly out to expose the electrical connectors. Unplug the connectors and work the light/lens assembly out of the dashboard. Finally, pull the compartment cavity all the way out. Installation is the reverse of these steps. Let me know if you need more FSM instructions or if you need pictures. -- 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.
