    Thanks for the tip. I inspected the vacuum system and found wires had been eaten at the vacuum pump plug. Repair wires and system ops check normal. Thanks again...

Sounds like you have a supply vacuum problem. When you lose supply vacuum to the control head it defaults to defrost.

I have a 2011 Chevrolet Equinox LTZ and my question involves the heating/ AC unit. The air flow seems to be very strong through the Defroster but for the dash vents and the floor it seems to be much s


Defrost has been stronger on all types. Just the way plenums are made. Clear that wind shield first. As long as you have plenty of heat to keep the cabin area warm to hot, it's OK. I wouldn't woory about it.

My ac unit is working but will not blow air out of the dash vents. The blower is working


Hey man if the blower is working and air is coming from your other vents i have a few ideas.First i would start by checking your vent selection switch something may be stuck where the dash vents open. If the selector is fine you should try checking the ducting behind the dash it could have come apart or simply be cloged where it routes air to your dash. hope that is helpfull.

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

1992 chevy g20 van ... AC blows through the lower ducts but not the mail cabin vents. What do I look for to fix this?


Behind the dash, when you throw the lever to change which vents you want air to come through, it can sometimes "slip" over little plastic gears/levers which flip the ductwork to different vents such as floor to the dash vents or defrost. look up from under the dash to see if the vent control switch is actually moving anything underthere.

Dash vents will not blow air. Defroster and floor vents blow fine.


Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.
