I am wondering what may be the issue on my 2004 Chrysler Pacifica. On the climate control you can turn the power on and off. However, the LED doesn't display and you cannot control the tempeture. It just blows cold air. The rear defrost does work but I don't think the front windshield defrost works. The fuses have been checked and are fine. Is this electrical or does the climate control need to be replaced. Does the climate control affect the car's computer at all?

Thanks

ac control head is faulty

 

So will the whole head need to be replaced?

 

pretty much unless u want to take it apart find the blue prints of the ac control head and see about fixing it yourself what ever the issue maybe.

 

My problem seems to be in two parts.

1) like the first post, in extreme cold, the heater blows cold, and in extreme heat the A/C blows hot, and

2) the vent diverters fail to rotate positions sometimes, such as not changing from floor to dash to windshield.
