A/C vent not blowing air

[BajaMark]

I have a early 00' silverado 1500 4x4 extended cab with the 5.3L engine. I just noticed that the farthest driver side vent does not blow any air. Im wondering if it is a clog, or if there is something really wrong. Not an emergency more of an inconvience when its ridiculously hot outside. Any tips would be helpful

you need to see if the center vents are blowing and the floor at the same time if so the blend motor is not working correctly. you can look under the dash under the radio and you gan see the motor. this one is the easy one to fix if it is the issue. othere than that you might have a clog but that is huge.......mike
