Need A/C Help

Hey Folks,

I have an A/C vent issue and was hoping that someone could help me out. My AC works fine and blows fine, but I can't control what vents the air comes out of. I found the actuator(not sure what's it called) that controls the vents. It went out earlier this year and I replaced it with a new one. A couple weeks later, it went out again. I replace it a second time. It ran for a couple months and the part went out again. I don't want to keep dropping $100 for this part every other month. Right now it just blows up by the vents/defroster area. I want it to blow through the vents to my face. I'm not sure how to test it if there is an electrical problem causing the short or if I'm just getting bad parts. I'd appreciate any help, even it its just to rig it so that it just blows through the upper vents. Thanks in advance.

Plenty of threads on this.
if you're only getting Air through the vents - you have a leak somewhere in the lines.
If you have 4x4 - I would first suggest unplugging (and sealing) that line that goes to the hubs - this will take the vacuum going to the 4x4 out of the equation.
1) if you have control of your vents back - problem/leak is in the lines going to the hubs.
2) if you still don't have the vent controls - then the leak is somewhere going from the actuator to into the cab.

The Actuator should only run for a short amount of time. If it stays on running - it will burn out and have to be replaced.

Mine's been doing the same thing. but its been random, sometimes it will work all the time then sometimes it will stop,

only thing that changed was the elevation could that have a factor?
