My cooling fans arent coming on like they should. Is it a relay? And how do I determine which one?
Could be. But check the wire from the sending unit that controls the fan. (I admit I stole that answer from dandyoun on a very similar question, and that was the problem) click to enlarge
I hot wired the fans to battery an they still want come on
My 1996 Deville had overheating issues. Bored hole through thermostat but then found out there was a small belt located under a cover that had broken. No one knew it existed and we found it by accident. I believe they said it was on the water pump. Small item but car runs well now and has no overheating issues. However, the ac/heating fan does not come on.... haven't fixed it yet as I keep getting if this and if that answers. Saw a video where tampering with the buttons on AC/heating could cause this too happen... actually, people pushing all those related buttons in the wrong sequence can cause this issue according to that video. Will get around to fixing it someday.
Under what cover? Can you pick it out from this? click for full screen
This is a different kind of pump. Not saying bad, just different
I went off topic for the relay location. I can't find the image as in the owners manual, can't copy and paste from a pdf. But Download and see chapter 6 Page 58 - http://justgivemethedamnmanual.com/cadillac/1996-cadillac-deville-owners-manual
I havd a 2000 Cadillac seville That fans will not turn on and the car runs very hot at time but it stays at 12:00 then moves up slowly when stoped in traffic once i start moving my temp moves back to 12:00 idk what to do n i need my car thanks
Ok here's what's going on. You have a fault code in your acm system that's what controls the auto climate, the a/c compressor and the engine cooling fans. First thing to do is turn the key to run. Press and hold the auto/econ button while simultaneously pressing the red temperature heat button. The system will the start displaying all ecm pcm tcs acm etc codes including obd. At the end of the list of whatever codes are there it will prompt you to pcm clear codes? If you press up (fan blade speed increase
I haven't tried this method yet, but I was wondering what else if anything could be causing a/c to blow hot air and cooling fans not working?
Hey KidCadillac Was this issue ever fixed? Also Jermery will this work for a 2002 Deville as well?
