    I've checked over the wiring for damage or corrosion, didn't find any, checked the blower motor resistor to see if it was blown, it wasn't, blower motor doesn't have any abnormal sounds coming from it during operation. The only other thing I can think of is that the blend doors may be due for replacement and it's blowing the fuses but I don't know if that would cause it. The main reason I know a fuse has blown is the air switches from any vent I want to only floor and defrost vents. It seems #55 likes to blow completely, but #39 the prongs get burnt.

    Hey y'all, I gotta 2011 GMC Sierra 1500 SLE 4Dr 4.8L V8 with dual zone climate controls. For whatever reason I can't figure out yet, fuse 39 or 55, the two that control HVAC, keep blowing on me. If it's not one, it's the other, they'll work when I replace them for a little bit, then they'll blow on me again. Anyone got any clue what could be going on?
