Code UP164 pulled...

[DeputyDipShizz]

So I just tuned my truck with the SC 3815...I checked the codes just for some gits and shiggles and pulled the above code...Which is interesting because I don't have a working temp gauge...ac button...rear defrost button...temp control...or blend door control for the last 2 months...The fan control however does work...I'm assuming this might be my problem...But...The fix?

U0164 Lost Communication With HVAC Control Module

Sounds like the switches are bad, that would be my first guess, would make sense with all the other problems you listed


(And this should be in the 3rd gen section not the superchips)

I figured since I just programmed it Id out it here...and the switches were already attempted with no avail

Have you checked relays and fuses?

 

[DeputyDipShizz]

Fuses yes...relays no...I'm no electrician unfortunately and don't like messing with that stuff to much

[DeputyDipShizz]

It will go to a garage for that unfortunately...Just wanted to check here if anyone has had the same issue before
