Question about 2003 Chevrolet TrailBlazer
The A/C and interior fan seem to be working fine...as far as its cooling capabilities. The problem I'm having is the four main dashboard vents aren't blowing any air out...period. I think the problem might be the air vent selector switch (ya know the knob that lets you select where the air comes out). The only hitch to that is it'll switch it from floor all the way to defrost, but when I select the front vents, all the air comes out the floor vents. This all started about two weeks ago when I went out to start my TB, which I had driven just that morning without a problem. When I tried to start it up, it clicked once at me and then everything went dead. I checked the voltage on the battery and it only had about 3 volts. Obviously not enough to start a vehicle. I got a jump from my neighbor and went on my way. During my trip, the voltage meter constantly fluctuated anywhere from about 10 volts all the way up to 14. When I got to my destination, my buddy took me to Wally world and I got a new battery. Problem solved. Haven't had a problem since then. However, my vents are still not blowing any air out. Any suggestions as to what the problem might be?
THE AIR SELECTOR MAY BE BAD BUT THE ARMS ON THE SIDE OF THE HEATER THAT REDIRECT THE FLOW LOOSEN AND WILL NOT OPEN THE FLAPPER, THIESE ARE LOCATED ON THE DRIVERS SIDE WHERE THE AIR BLOWS OUT ONTO THE FLOOR ABOUT HALF WAY UP.
