I’m on my 5th climate control module in a week.
It seems like something is grounding out possibly but have no idea where to start. The AC and Recirc buttons do not light up at all once it goes out. Blower, temp control still work. No power going to compressor to kick it on after the short. Tried jumping high pressure and low pressure switches with no luck. The problem lies with the control module and it’s wiring my guess. It will last at best 1 day or so before it goes out.
Attached you should see the only indication of a problem on one of my control modules. Another one looked completely fine. The first had melted the transistor underneath the switch for the recirc.
I have seen other post on this but nothing certain other than the posts on the transistors.
I really don’t want to open the dash to look for exposed wires but I may have to at this point unless someone can give me some solid pointers or systemic troubleshooting.
I checked my connections in the pigtail with the ten wires on the right hand side of the control module but nothing was bare, crimped or mangled.
There are no blown fuses in the cabin or under the hood and the ac relay is fine.
Really at a loss here as it’s mid June in Texas.
Any help is welcomed.
Thanks,
Matthew
