Hey Josh...sorry to highjack your other thread...hehehe


Anyways have you checked the vacuum connector that goes into your A/C controller?

Look for collapsed vacuum nipples.....don't laugh thats what we call them around here

Sure do. But airmix actuators have nothing to do with air direction....

Good question though

Josh also check the vacuum canister under the front right corner of your front bumper.....

It should have vacuum all the time. Pull the violet colored vacuum line off to listen for a vacuum purge sound.

Josh the controller is located under your passenger side dash area. Do a search here for 'trailnuts' it shows the controller and location.

Oh boy.....trailnuts...collapsed nipples....are we talking in code here.

All new members reading this post, please be assured that these terms are not in anyway perverted. They do pertain to car components.
