#38 of 41 Re: Power Window Problem [br20000007] by teachtech Aug 26, 2009 (9:45 am)
Replying to: br20000007 (Mar 21, 2009 11:50 am) I think that the response by bolivar "motor died" is wrong, since the window did go down. I just had the same thing happen to my '98: The driver's window went down, but not back up. The other 3 window switches all work fine. It turned out that the switch failed. I pulled the switch assembly out & tried to clean the switch contacts, but N.G. The Cadillac dealer wanted >$175 for the switch assembly (they are PROUD of their prices), but Advance Auto was able to get one from the OEM manufacturer for ~$100. NOTE: Both Cadillac and my local garage said that the book calls for 90 minutes labor to replace the switch (probably claiming to have to take the door apart). I just pulled the entire assembly (including the side mirror switches) up from the armrest, unplugged the cable, unplugged the switch assembly, and then plugged the new switch assembly in. It took me a total of 4 minutes, and I did it in the dark with just the interior light on! Hope this helps....

Replying to: 97_deville (Jun 25, 2009 8:23 am) I have a 2002 DeVille which started giving stalling problems at stoplight idle around 100K miles, now at 103K. Mechanics could not find any problems, so we replaced the IAC and EGR valves ($900) but still have the problem. Now getting hard to start. Any other solutions? No stalling at speed, only at idle, and only after warmed up. Stall is sudden, no rough idle. I hope yours stays fixed.
#41 of 41 '89 DeVille starting problems by rich_c Oct 29, 2009 (10:28 pm)
I have an '89 DeVille with 77,000 (actual) miles. 1½ years ago, I had a problem starting it after driving about 5 miles, then parking for a few hours. I waited about 15 minutes, then it started immediately. All was fine for about 2 weeks, then it did the same thing. Waited about 10 minutes, and it started right up. Happened about 2 more times, took it to my mechanic, where he changed a "module". Everything was then fine for about 6 months. Took it back, he replaced the module again, and all was fine for 4-5 months. It did the same thing again, but my mechanic said the part supplier "checked" the returned module, and declared it was "fine". Now they won't replace it unless I pay for a new one. Any ideas?
