Hello there is a actuator that needs to be replaced called a mode door actuator. It controls the temperature coming out of the vents. Since the rear ac is ok that means the system is charged and the compressor is working since both systems share the same compressor and lines. Part of the dash will need to come out for this to be replaced. It is somewhat of a medium difficulty job. Hope this information helps. Let me know if you need anything else. Lou.

do you know how much freon it takes with rear AC ?
Expert:  Lou P. master tech replied 1 year ago.

I would need your vin for that. You should have a sticker in the engine bay that tells you the quantity of freon both for single and dual ac. It should be about 2.5 lbs but don't quote me on that.

Expert:  Lou P. master tech replied 1 year ago.

Also like I said if the rear is working then the freon should be fine. If it was low then the ac would make a howling noise and you would get some cold and some warm together.
