Question about 2003 Chevrolet TrailBlazer
Posted by Anonymous on
If you hear an unusual noise coming from behind the glove box, there could be something in the blower fan. Remove the lower panel (3 - 7mm screws) then remove the glove box (2 - 7mm screws). Disconnect the electrical plug from the fan blower motor (2 pin connector) and the 3 screws holding the motor (5.5 mm screws). The motor slides downward. Inspect for debri in the fan.

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
