Vintage Air Blend Door Problem

[70TWO NOVA]

Ok, so I just finished installing my gen 5 vintage air system into my Dads 1980 Camaro and when I turned everything on for the first time I was only getting air out the floor and defrost vents. When I switch to "dash" it stays on floor/defrost. No matter what I do with controls it will not change to dash vents. I read through the troubleshooting and made sure the system was mounted properly as to not bind the box and thus the blend doors. Still nothing. I rechecked all my wiring and even the stepper motors that control the blend doors and coudnt find anything wrong our out of place. Is there something I'm missing? Something else I should check? Any help is greatly appreciated

What controller are you using? A friend of mine used a Dakota Digital controller and had a problem. Turns out one of the pins pushed out from the connector. I might add that VA's tech line is very good. Maybe go that route.

Iam using all Vintage Air stuff, after a couple conversations with Mark Hungerford I was able to narrow down the issue and get it fixed last night. I have to thank the guys at Vintage Air big time for the quick response and willingness to help fix this.

Just for the record, what was the cause of the problem? Best if in the future someone looks at the site for information he sees how a problem was closed not just that it was closed

To be honest I dont know what caused the problem. What I had to do is stick a long screwdriver throught the vent holes to force one of the blend doors open. For some reason it was stuck and would only move about 20%. After some effort I was able to get it moving again. But once again, I dont know why this door was stuck in the first place. This was a brand new unit strait from VA right out of the box. Works fine now.....so far

well it worked for about 2 weeks, and got stuck again. This time I dont know what to do. I double checked my mounting and made sure the box wasnt in a bind and tried to do the same thing as last time to get the door moving again but to no avail. It will only work on floor and deforst, which totally sucks since we live in Phoenix, AZ where it is currently 110 degrees outside.
