A/C air flow stopped switching to panel, comes out defrost instead, it will switch to foot area?

Hi,

The mode door is what was responsible for airflow direction. On this vehicle, it is controlled by an engine vacuum.

I need to confirm something. Are you able to change from defroster to floor? Also, take a look through this link. You may find it of interest.

Let me know.

I did some checking and found out where the defrost mode actuator is located, it is working so that left out the vacuum issue, it did change from defrost to floor, i removed the dash cover around the radio and ac controls and reached in the duct on the right of the radio pushed the door open and got air flow, switched to defrost the door closed, switched to ac and the door stayed shut but the actuator pulled in which confirms there is vacuum present and it is working, here's the rub, when I reached in the duct to open the door to let airflow to the panel this time the door fell off and inside I'm guessing a busted hinge, that might explain the thunk noise I heard Friday on my way home from work, the door closed when i shut off the A/C and Saturday when i turned it back on the problem started, I am guessing I would have to pull the dash to access this issue, I might do that if I ever have to change the evaporator, as it is the heater core is bypassed, was when I got the truck and living in Florida I don't need it, for A/C I would pull the dash, let me know if there is a way to do it without pulling the whole fricking dash. Thanks, Kevin.

That certainly sounds like the problem. Are you able to replace it or even access it?

Let me know.

Joe

that was my question, can I access it without removing the entire dashboard like I would have to do to change the heater core or ac evaporator.

Hi:
Yes, the heater box will need to be removed. I've seen people cut into their dash to access, but it makes a mess.

Also, I believe the AC freon will need to be recovered and the coolant will need to be drained.

I wish I had an easier answer. My manual doesn't provide directions for replacing the doors. The only thing it has is the labor rate, which is 6.9 hours.

Let me know what I can do to help.

Take care,

Joe
