My A/C control unit on my 03 Silverado is stuck in defrost, temp control stuck on hot. The fan 1-5 works. Recycle, A/C, and defogger has no power. I  checked the fuzzes and nothing wrong there. I just replaced this unit a month ago and it was working fine until one day it just stopped. Any thoughts on what to do here?

If it was a Dorman branded unit, find a used OE one to replace it. It's junk.
