I haven't been able to figure this out, when if I have it completely off and want to turn it back on, it wants to turn my AC on!! That is not good for the compressor to turn off and on like that. I have tried mode, ac off and on button, auto, etc. Any hints?

 

GM claims it is good for their compressors.
Keeps 'em lubed.

 

same thing on my 1st gen ... i go to put defrost on and the ac turns on !! wtf

MaCe

 

Didn't you know the best setting to defrost is to have heat and ac run at the same time?


Speedy,

Try to the press AC button to set AC off and turn the right knob (fan control) to a different setting.

 

what if i don't have a knob. i always have to get my screen dirty to turn off the damn a/c.

 

the A/C dehumidifies the air which is why they do that... helps clear the windows faster. Unless your a chain smoker then your just screwed anyway...

 

You are gonna have to ask one of the guys with Navi
