I have a 2003 trailblazer EXT LT. the front AC/ Heat controls work when they want to. they fan will run after the car has been turn off for as much as 3 hours. or it will not work at all. I checked the fan...


If you have automatic climate control, replace your blower control module, behind the glovebox.
If it's manual, replace blower motor resistor assembly, same location.

2003 trailblazer I have no heat or air coming out of my dash vents


Is it no heat/air when sitting still, or no heat air period? If the heat and air blow slightly when driving you have a bad blower mower/resisitor and its not allowing the air to blow into the cab. If not blowing period when moving probably bad heater controls or fuse... Worst case scanario is you have an electrical problem that needs to be diagnosed
