Having problems with your 2002 Chevrolet Tahoe ?
Ac seems to come on but air not blowing through the vents. the fan is working. i can hear it but nothing comes through the vents. you can feel some cold air coming from behind the dash.
Check for a broken vacume line under the hood find the vacume canister should be eather on the right or left side under the fender its a black round ball shaped with 2 hose's one in one outif the line is not attached or is leaking then you do not get any air
Try your heater box door it may be stuck closed or it could be vacum lines.
