The rear A/C blower is not blowing air. If the speed control (mid van ceiling) is changed there is no change in blowing air or sound at the rear vents.

The front system blows cold air out the vents but you can feel very hot air at the floor around the console and front seats.

The rear fan control on the dash appears to work, i.E. The noise level changes as you turn up the speed, but there is no change in output at the vents.

Please advise possible problem and location.
Thank you.

You will need to take apart the rear side trim to get to the rear HVAC box. It sounds like the motor may be going out or that the doors are off and it wont let the air blow out strong. Possibly a bad fan blade (squirrle cage) on the fan motor. The heat up front, be sure the engine cover is secure, it sounds like it isnt seated good and hot air is getting in from the engine

I removed the panels and found the door is shut (lying flat) which is venting air along the floor and bypassing the overhead vents. The actuator is getting vacuum but does not actuate the door. It appears that the door is not connected to the actuator. I would say that the door attachment to the actuator shaft is missing or broken.
The door can be raised by hand to close the floor vents and open the overhead vents but when it is released it falls back into the overhead closed position.

What parts/assembliesare needed to repair this condition. Approx. Cost?

Is this system strictly A/C? Is door to change air flow to heat along the floor in the winter? (There looks like a small electrical heating coil above the door.

What are the ramifications of permanantly locking the door in the up position by installing a screw through the side of the box to prevent the door from closing?
Thanks

There are 2 doors back there, 1 for vent control, 1 for temp. If you wedge that door so it only blows through the upper vents, then it shouldnt change the temp settings. Try it before you put anything back together to see if it is ok temp wise.
