Having problems with your 2004 Chevrolet Impala ?
The dual climate control for the drivers side is stuck on cold. I assume it is one of the three accuators under the dash or may be more than one. Please provide instruction of the best way to get to these and change them out. The blower has stopped working a few times but you can slap the dash pretty hard and get it to turn on. It also fluctuates presseure high and low as your driving. Please fix this!
I work as a gm technician, and have dealt with this many times. The actuators rarely go out. What I have found is the hvac control head in the dash goes out. You can get one at a junk yard, or local dealer. you to remove the plastic trim panel around it, and a few screws that hold it in and it just un plugs.
