There are what they call mode door's these days they have a electrical motor that turnes the door to different posistions...sounds like yours is become broken. It would depend on your expertise in the ac & heating system area to replace the part. Sometimes easy and most of the times the dash has to be removed.

1995 chevy silverado heater blower blows but cant feel any air no where


Possible that the vent is blocked or there is fault in the vent selection. You need to remove the blower unit and check the area of the distribution hose.
make sure that the selection panel control works or this can prevent the air to be blown out.

maybe drop the blower motor and check the vents for obstructions. I worked on a friend's car this spring that had a two year-old repair bill sucked in to the blower wheel....it limited the air output but made a lots of noise in the process.

1995 Chevy k1500 heater problems.


For a 95 Chevy Silverado....I replaced the Blend Door Actuator on the passenger side. Just behind the slide out cup holder. Yo ucan acces easily by removing the ash tray piece and the glove box....Or just the glove box and work like hell to get a socket in a tight place.

There are 2 actuators....one controlling the (Mode and Temp 89018681) and the other the (Air Inlet 89018367). I called the dealer and the parts were 85-125. I got it From TBA Auto (local store) for 39.00. A 20 min job at most.

most american cars force the defroster to blow cold air, this is not a problem, it does this by design.
