1995 chevrolet pickup, air only blows from the bottom air vent and not the top vents.


these trucks have 3 actuators. none of these other people have a clue obviously. theres one directly to the right side of the gas pedal. theres another one directly behind the tape player deck. there is a third one behind and just below the glove box. the one behind the tape deck controls between hot and cold air. the one near the gas pedal controls A/C. the one beneath/behind the glove box controls where the air blows. please dont believe these people. there is a video on youtube that shows the location of all the actuators and shows the actuators while installed in their place.

Drivers side vents are blowing warm air when in the A/C mode. Passengers side vents blow cold air.

Driver side air on the duel climate control is blowing hot and the rest of the vents are cold


Joey i had a similar problem in my 2000...The problem lies in the A/C Actuator. The Actuator is what opens and closes the vents, when the vents are open it allows hot air to flow through and when thier closed it prevents hot air coming in while air conditioner is running. depending on the year some vehicles require an upper and lower actuator. they are fairly simple to replace, and dont take much time. most actuators are located under the control switch box (radio, a/c dials) parts run about 60.00 each.

The driver side vents are blowing hot air as if the heater is on but the thermostat is set on 65 and the passenger side is blowing cold air as it does normally.


Its called "AC Vent Door Actuator" when this fail they will stay open or Closed, this will happen on vehicles that have Dual Climate control. You can Google it just type Year, make ,model and AC vent door actuator after that. It will definetly have to be replaced. Good Luck.

There's warm air blowing out of the driver-side


Most of the time the dash has to come out to access the actuators on the heater box.
