I have a 1996 Chevy Silverado. Im having a heater issue, the heater is not blowing hot air, the fan speed control **** works but the temp control **** doest not as well as the vent selector. It seems to be stuck on all vents and cold air only.
Ive changed the T-stat, heater core and checked all the antifreeze. It just stays cold and will not select different vents, I also checked and the door actuator is getting power as well as the heater control itself. Im lost at what to do now
