SOURCE: There is no air flow

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!

Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!

The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!

I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!

Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!

3 on the Drivers side and 2 on the Passengers side!!

But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

SOURCE: 1995 Chevy k1500 heater problems.

there is an electric motor that moves the linkage to change where the air comes out..its under the dash to the right of the gas pedal........the problem is likely the linkages form that motor to your blend door that directs the air.its called the Heater Blend Door Actuator
hope this helps.......Good Luck!

SOURCE: 1996 chevy blazer my air on heater will not blow

the idea of the switch is run on vacuum and is not making contact with the switch it self either worn contacts in the switch itself **** as an obstruction as well or the vent door is stuck in just that position either behind the glove box or the ash tray are the vacuum lines one of them may be pinched off or the door needs a bit of help until you can free it up

SOURCE: All Air Conditioning blows our the defrost vents

Some thing you could look at would be this. The control is usually fed by a vacuum line or small hose thats is connected to your intake manifold.
With a cold engine,look for a skinny vacuum hose that runs from the intake toward the fire wall . It should be going inside the cab and connecting to the A/C vent control.Some times the hose becomes disconnected or splits or cracks due to heat under the hood.
Thats usually the trouble.
I hope this helps you.

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.

Low power when accelerating


I thought the filter might be the issue here, on carb cars the engine tends to stall out with a plugged filter.

your controls have problems. the heat is there it is just not getting out because your control lines are not setting the vent controls into the proper positions. i had a chev van that lost some of the foam in side there and it blocked the whole front off. i had to rip it all apart to get at it
