No heat
My blend air door is stuck on my 2010 liberty. I have removed the actuator panel on the drivers side and the middle door that controls the air flow to the dash is completely seized. There are 4 blend air doors on this liberty, 2 control the heat/ac and 2 control the air flow.
there is no access to them from the drivers side and the passanger side looks like I have to cut into the air box to get to them.
SOURCE: Blend door not working.
The bleed door controls air temp not where it comes out, dash, floor, defroster, this is most likely a mode control switch problem, that switch is on the ac control head.

please elaborate, does your inside fan still works? does your compressor clutch kicks in?...would you know if you have refrigerant in your system? if you can trace the hose from the compressor to the evaporator, you can see a plastic cap normally blue with a big letter "L" at the top, then it is the low side fitting, you can remove the cap and get a pin and press the pin at the center( be carefull, refrigerant might be present). if there is none, then you have a leak. u lost all of your refrigerant that is why the ac did not work. if you do have a big burst of gas as you press it, then it is not a refrigerant problem,
a lot more to be tackle as you help me diagnose your problem.
tnx

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.
