That is correct, the air blend door actuator. "flapper valve" may need to be replaced or cleaned and free from binding up. Good luck and hope this helps. If there is an Auto Zone in your area, they can order the part you need and give you the step by step instructions to removing the old actuator and replacing it if it's damaged. Good luck and keep me posted, be glad to help.

SOURCE: the ac blows hot air in the front and cold air in the back

Either the door that controls whether air from the heater or ac is stuck in between or the ac system is having trouble. Minivans sometimes have seperate compressors for the rear and front.

SOURCE: I have 2001 Pontiac Bonneville My heat works but

Your passenger side temperature door actuator is bad. You can access the actuator by removing the glove box & hush panel. The actuator is on the side of the HVAC box. If you can gain access to the actuator watch the center of the actuator as you change the temp on the control head, if the actuator does not move it is bad, if it does, the door inside the HVAC box is bad. Most likely its the actuator. If you remove the actuator & open it up you will most likely find the large center plastic gear is cracked all the way through. It is held in place by 2 or 3 7/32 screws. Once you replace it, disconnect your battery wait 30 seconds and reconnect it to reset the HVAC control head so it can relearn your actuator positions. It can take up to 5 minutes for the control head to go through it's relearn procedure. You can try resetting the actuator first , but make sure your radio is turned off before you disconnect the battery and if your luck, the actuator may not have any broken parts and the gears may just need to be freed up and lubed. Good luck friend and hope this helps.

Need location of ECU for pontiac g8


Hi there:
It is located in the engine bay, lift your hood. Look behind the passenger-side headlight. Under the fuseblock.
The silver finned block with the two huge wire bundles hooked to it is the ECM.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

HEAT ONLY BLOWING WARM AIR ON PASSENGER SIDE


have someone check the driver's side temperature control doors, in behind the radio. there are two push rods attached to a plastic piece. the connector on one or both of these push rods, become unattached. leaving you with cold air. once that temperature door is closed you get hot air. passenger side still mixes, but not drivers. All or none for heat on Driver's side

AC unit blows cold on passenger side and warm on driver side.


Hi,
There are separate blend doors for the passenger and driver's side. The blend doors divert, not block air, so it is unlikely that the blend doors are the problem. You need to check the operation of the re-circ door.
There may be some more duct work that attaches to the heat/air conditioning housing under the dash, that supplies air and or heat to both the driver side and passenger side of the car, the duct work on the driver side may have come disconnected.Check this also.
Hope this helps
Thanks
Smith.

Front a/c problems


There is probably a temperature blend door in the duct-work under the dash that is inoperable or stuck in the heat mode.

Heat works on driver side, passenger side blows cold air.


Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.
