to me this is a difficult one. I got the car from a friend and the pump for the air ride wasnt working. before i could get it replaced the cooling fans quit working so i thought a relay was bad cuase the fuses were good.so i replaced all three relays that were under thee front of the car and nothing . but i know the fans work because i wired them direct and they work so the next thing to me was bad power or ground so i got the light tester out and it is getting power and they are grounding and i thought maybe the coolant temp sensor but i get a coolant temp reading and i am told that it is the same sensor but that aint all my dash says service- emissions and sometimes ignition the cruise doesnt work and when i was check the wire for good grounds i had the key on and not running but the o2 sensors were getting hot so i still assumed that there is a bad ground so i checked the grounds and put 2 new ground straps and that didnt help nothing so i am kind of lost and thinking that there might be a problem with the pcm. so i would appreciat the help be cause i just had a baby girl the 16th of oct. and cant keep throwing money in to it and cant really afford to take it to a garage

edsauto,
It has been a while since I saw this problem so I'll try to point you in the right direction. GM offers an updated wiring harness/repair kit for the air ride system and ABS system(separate). Contact the Cadillac parts dealer with your VIN number and inquire about a splice kit.

Good Luck,
