SOURCE: 2004 Pontiac Montana blows cold air in defrost

There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!

There are seperate blowers for the front and rear air. It is most likely either your blower motor or the resistor, both located under the passenger side dash. I got a blower from a salvage yard for $25, But ended up having to get the resister from the dealership for about $130. Hope this helps.

Item Part Number Description 1 — Air inlet door 2 — Temperature blend door 3 — Headliner airflow 4 — Auxiliary mode door 5 — Floor airflow 6 18476 Heater core 7 19860 Evaporator core 8 19805 Blower motor
The auxiliary A/C and heating system has the following features:

  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
---------------------------------------
I would say the auxiliary mode door (#4) electric motor is not wokring.

=============================================

  1. Disconnect the blend door actuator electrical connector.
  1. To install, reverse the removal procedure.

SOURCE: ac vent problem

Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.

Front AC cold but Rear AC very hot


Not likely, but Is Hot water flowing to heater coil in back? How hot is "very hot" Is it a refrigerant line? If a refrigirant line, Very Hot means it is hot gas from the compressor that "should be going to the condenser coil usually in front of the radiator. It's almost impossible for that Hot refrigerant gas to go to the cooling coil in the back unless you had some repairs done and they weren't certified. My guess is the radiator hot water is not being controlled properly, due to bad valve or control system components.

There is a separate button on the lower dash labeled RR HTR for the rear heater. If you do not engage the switch it will blow cold air.

Air vent heater


Check the vacuum can on the ac box. It may just be a broken vacuum line or the can can be bad. There is a baffle in there that has to move from AC to heat. Sound likes there no vac getting to the baffle vacuum can. Could also be the switch in the dash board controller. Depends on what type of car it is.
