I have a 2004 Escalade and the climate control will only blow cool air from the dash vents. The air temperature will not change and it will not blow out the defroster vents. any ideas?
No vacuum worked stuff in these systems(that went the way of the dodo back in the late 80's early 90's)Roger Number 1 said:I was thinking maybe a vacuum leak?????
I think the brain module is behind the control unit but I will have to check my gm service manual to be sureRoger Number 1 said:I wouldn't think it would be the temp sensor because the fan speed changes when I change the temp setting. Where is the control unit?
