SOURCE: 1997 jeep grand air blend door location

The Jeep Grand Cherokee sucks air from the outside via a hole on the passenger side of the cowl. It's under the black plastic piece that runs under the wipers.

The air is then sucked via the blower and blown into the housing where the heater core and A/C evaporator core live.

The blend door is inside this housing as well.

This also depends on if you have regular climate control or the more advanced ATC digital climate control found on some of the Limiteds.

You could possibly take out your glovebox and see if there are any broken pieces going to the door accuator.

Otherwise if it's internal, you'll need to take out the heater/ A/C housing.

To get to this housing, you have to take apart your entire dash, lift the top dash cover off, and then you'll see the housing. You could possibly check for a few thing there.

Most everything there is vacuum controlled.

You have to drain your antifreeze and have your A/C freon discharged (use a professional to capture the freon).

There are 5-6 nuts holding the housing to the firewall. You have to reach these from the engine compartment.

Disconnect your A/C lines and heater hoses. Pull out housing.

This is definately an advanced project, thus the reason for the high pricing.

Hopefully you can get it fixed without having to take this Jeep apart entirely. Try diagnosing with a vacuum gauge if necessary before tearing it apart.

1995 GMC JIMMY AC AIR FLOW PROBLEMS.


Usually a blend door problem.
The system is designed to default to the defrost position for safety.
If the blend doors are vac operated, look for a vac leak.
If electric, look for a failed motor or stuck door.

Vents blowing constant cold air...told it was the blend door on my 1999 GMC Jimmy ....replaced thermostat.....flushed system and replaced cracked radiator....heater coil is not leaking. A/C is a seperate...


Its more than likely the blend door not moving to the heat position. I'm not familiar with the location of the blend door in the 1999 GMC jimmy, since I'm not a mechanic and don't have a manual on that vehicle. If you can get to the blend door housing you might be able to move it physically.

1999 jimmy cycles form hot air to cool air constantly


This sounds like possibly a broken blend door on the heater box assembly or possibly a vacuum problem if the blend door is controlled by vacuum.
