no heat or a/c please help
 

i have a 1994 Cadillac deville concurs my climate control like doesnt work when i start the car it comes on and then just goes to dashes where the temp should be and for the outside temp everything else works i can still go into my look at my codes and everything but when i pull the codes it say no apc data i dont know what to do the dealership said that i need to have the climate control module fixed which will cost around 400 bucks and i dont have that kinda money

Check grounds if OK, try the salvage yard. ACMs do not go bad very often.

sorry it was acp data i am pulling ground problems for my suspension but thats all but i dont see how going to the junk yard would help because the ccc is conected to the rest of the instrument panel from what the dealer ship told me?


so i'm unsure it you could explain more about what you mean i may understand thanks

ACP is the programmer. ECC is the control head its only the messenger, and part of IPC. What codes are stored in other modules?

RE: no heat or a/c please help
 

the only code i pull for the hvac is I037 and the rest are SO codes which are suspension

From info posted, check G305 at right kick panel if ok, try a new programmer.

RE: no heat or a/c please help

You need to invest in Factory Service Manual (both volumes) it seems your over your head. It will be able to guide you in repair and how stuff works.
