Hey guys I'm new here and have searched around but find very little on 07 silverados. Maybe someone can help. My blower won't come on at all. I've replaced the climate control module and hooked the blower directly to 12v. The blower works but nothing when trying to control it from the dash. Fuses are good. I have 12v going to the module or resistor (seen it called both). Is it possible the digital controller in the dash is bad? Any help would be greatly appreciated.
