When u switch the air from floor to vent do you hear, like , a door closing under the dash? You could just have a simple problem like yourclimate control switch is bad. Or since the door that opens and closes is ran by a vacuum line, one of those lines is pinched or it came off. Check and see if you can switch the air to anywhere else.(floor, floor and vent, etc)

Trying to get the air sto blow out of the vent


The system uses a blend door to direct air thru the vents. Your car uses an electric motor to open and close the doors. They are in the HVAC box under the dash.

1999 tahoe wont blow air out dash vents


my issue at the moment is that the linkage (control arms) have come apart. it looks like there's a part missing from between the two control arms. there's a small electric motor with one arm and another arm that controls a flap somewhere that shifts the air flow between floor and up top. both of these control arms have a square hole in the ends and i don't see a way for them to be reconnected. so i'm assuming that there's a part missing.

Dash vents will not blow air


It may be the mode actuator. Have you heard any clicking or other strange noise ? Under the drivers rear seat, in a plastic box is a fuse panel. Remove the two retainers, and the cover. Remove the HVAC or A/C fuse for a minute or two. Reinstall the fuse and this will make the A/C system relearn. Whwn you put the fuses back do not touch the A/C controls. Start the truck and leave it run for two or three minutes. Then try to change the vent from floor to vent and defrost. If this does not work you will need a mode motor. Good Luck

Air conditioning


check your vacuum lines that sevice the plenumm doors that redirect the air. A good kick in one of the foot wells under the dash can dislodge a conection. The other problem may be the main dash selector its self
