East302 have a question how do you get to this part in the picture? On my 96' the arm on the left keeps popping out up top and I have to crawl under the dash and re attach to get my defrost to work on driver's side after switching modes. Is there any easy way to drop that box?

The dash has to come out to get to it. The silver arm is pressed onto the damper arm, so until you can get it open it’s probably going to be hard to get it to stay.

Meaning - you’ll need to put pressure against the opposite end of the damper or it’ll crack the plastic housing. Trouble is, getting to it may be a challenge.

I’d try some epoxy on it, maybe that’ll hold a little longer.

See if your actuator arms are reversed. The front one is shorter than the one in the back by the firewall. That’s a guess, but it sounds more mechanical in nature (or a flaky a/c panel). Compare the silver dial position indicator notches to the photos below.

Kinda what I figured thanks for the reply, I'ma try some epoxy before I remove the dash for sure.

Dash removal isn’t really a big ordeal, but you might as well address the whole a/c while you have it down.

Just time and money...the usual things.

how easy is that dash part to get off..im not getting defrost still..

 

[vendo]

I looked at the flapper at night in the vents and i see it opening only a little bit..is it easy to take the box down to see?

Which flapper is not moving? Test the mode door first

with help from a friend it looks like the acuator is not centered,goes more one way than the other..could the switch console make it not go all the way one way,the defrost side will not go over enough..

 

[warndogg]

No, probably not. The actuator is probably bad or something is physically blocking the door/flap. It should not move beyond the 2 detents on the actuator. With the actuator off you should be able to manually move the door. If you can't you will need to remove dash and fix. Hopefully you just need an actuator.

 

[vendo]

i can move it with the actuator off and defrost works,can you index them if you take them apart?

 

[warndogg]

You may be able to fix the motor by taking it apart. I think there maybe might even be a post or two around here about that. Honestly If you have the cash they are under like $40 I would go that route.

 

[vendo]

ok i will get an ac delco one...i just wonder if the newer a/c control using the wiring harness was the issue..

 

[vendo]

my acuator is in the middle when i put it on defrost,the pictures posted shows the pointer on the right most line of the 3.

 

[warndogg]

The new one? If so take it off while in center (middle) position and manually move your vent until you only have air at floor then put the actuator back on and it should work.

 

[vendo]

no the old one,should have new one tues..

 

[vendo]

i put in new one and it works now...got a GM one..
