Ventilation Clogged

[shaynehardy]

Hi, i am wondering if anyone out there knows how to blow out the ventilation system in a garge with a compressor. im talking about the vents that blow hot/cold air to warm up or cool off your vehicle on the inside. mine is quite dusty and smells terrible, i just dont wanna pay big bucks just to get someone to do it.

Maybe a shop vac will clean the dust from the vents. The musty odor is most probably caused by a clogged evaporator drain. It's where your heater coil is, in the cab compartment. You will find the drain hose underneath vehicle, where you see condensation dripping in the summertime. A lot of people have success blowing compressed air up into the drain hose and maybe use a clothes hanger. But don't punch a hole in the heater coil. I haven't enjoyed that kind of success. I'll normally pull the heater coil case apart and hand clean the drain.
