Wiper Door and Vent Question
Finally some decent weather and got the car out of winter storage. When I start up the car, the wiper door lifts for about three seconds and then goes back down. Where should I start looking for vacuum issues? The door raises and lowers normally with the bypass switch.
Temperature was almost 80 and it was getting a little warm in the car. I pulled the little vent lever but got no air. Is that vent vacuum controlled or is it a cable?
Thanks

The wiper door park switch is the usual suspect, also worth looking at the check valve (since it's easier to check/get at)
For your second question... Which vent lever do you mean? the one on the dash beside the *****, it needs the car to be moving, there's no fan or anything on those
The ones on the shifter console, non-AC then the same, they just let air out of the kick-panel from the wiper cowl area, again, no fan

Here's a good write up on the door opening and closing on startup (there's a lot of these if you search)

This is a non-AC car and the levers are the ones on the shifter console. I always got air (mostly hot air) when I pulled those levers but yesterday, I got nothing on my side. Didn't check my wife's side because she was actually enjoying the extra heat.
