On the AC- Heater Control Unit Switches (3) - PANEL in the center of the dash... The left switch that controls the temp. for the cold and hot... has a problem with the left side (blue color side) AC - cold part. You can move it a little and it stops blowing cold air... move it a little more
and it starts again??? Anyone know if there is part to replace JUST this switch, without having to get the 3 panel with all 3 switches from the dealer (400.00)? Is there an aftermarket part for the 3 panel ...OR better is there just the switch for the AC - Heater (far left switch with the half blue, half red colors strips)
for controlling the AC and the Heat? I CAN find the CENTER switch for the fan speed control (which is replaceable) BUT not the other 2 end switches. Any one know of an replacement part(s)? Anyone have this problem before? AND YES... I can get it in a run place and it will run and be cool... so far.
Hope it keeps doing so as it's to be 100 degrees by end of the week... for the members way up North that is like being at the other end of "- 0" frozen scale!

 

a used one from EBay should get you going.

 

$65 on ebay, assuming you don't have heated seats. https://www.ebay.com/itm/31428069021...Bk9SR47AtqaWYg
But I would pull it out and look at the wires first, since there is no connection between that knob and the blower or the AC compressor. It just controls the blend door. The mode selector and the temp control go to logic in the switch assembly, the blower control does not.

 

Thanks for the info from Blue and Brew, found some on ebay. Here is a good video on replacing the AC/Heater control panel.... Someone may want to move / copy that to another area where
it may get more viewing. Also a note that the Wells Electric Co. does make the center blower switch (new) and if that is the only switch bad then you want have to get the hold panel used. SEE this video on that problem and replacing the center blower switch and
getting it from Wells Electric (part numbers and applications etc.) SEE info at .... Wells Vehicle Electronics: http://www.wellsve.com/
This video is about a Cobalt but if the part shown doesn't fit you can check thePart Number on your Switch and Cross Reference to a Well's Part Number or another brand(s). Hope this helps and I called Wells for the switch I needed but they couldn't find it (they say
that they make 300 or so new parts a months)????? When looking for parts I like to call the makers and talk to the tech guys, sometimes getting more info on lots of things.... Good day members
