: No heater or A/C Controls

10-07-09, 08:02 PM
The heater and a/c controls on my 98 Catera just shut down. It appears there is no power going to the control at all.

I have checked all fuses and they seem alright.

This just happened one day when i started the car it had no controls for the heater or a/c.

Since this happened the other day when i started it the controls came on and everything ran normally. The following day when i started it the controls where dead again.

Would anyone be able to give me an idea of where to start.

With the greatest of thanks Keith

Try that 20A fuse that says CIG

Was it the CIG fuse or the Haz? I can't remember, haven't had to pull it since I installed the new outdoor temp sensor
