So, everytime I start my car when cold, my sunroof and ac/heater don't seem to work, after a few minutes of driving my car, they come back on. My cd player, lights and everything else work. Has anyone else had a problem like this or know where to start to look for my problem. Any help would be appreciated, thanks in advance.

 

i know that some of the hvac stuff is on a breaker instead of a fuse down in the fuse panel by the driver's feet... I dont know about the sunroof. Things like the heater rely on the coolant being heated up though, so until the car is warmed up, you wont get heat blowing out of the vents.

 

No its not that I don't have heat, theres no air blowing at all. No power to it whatsoever. I don't have the vent piece in thier right now, so you can see the little flaps in the back move when you switch it to defrost. Those don't even move. So for about 10 minutes before the car warms up, I have no power to the sunroof or the hvac.

 

well those should both run from the same constant power source, comes off ignition to only work when car is in RUN pos, check the FSM and see if you can trace the wire, for only working after 10 min or when car is warm that sounds wierd, nothing having to do with car warming up should 'warm up' the ignition power, dunno, i do know the radio will work, its a different circuit, runs on ACC power, like i said search for the FSM (factory service manual) they have just about any wiring schematic you can think of... good luck, wiring can be a real bitch...

 

Okay, so maybe after the car warms up and it starts working is just a coincidence. I'll check the fsm. Thanks for the help
