Air recirculate button stuck
 

The air recirculation button on my non a/c 85.5 is stuck in the "in" position, which I assume is full recirculate - so no fresh air coming in. Is there any way to remove the switch from the heater control panel and attempt to free it?

Nope. It would be easier to remove/manually open the flap that closes the air intake under the hood.

The switch would need to be desoldered from the unit, after tearing it apart.

I would try a touch of silicone spray on it and see if that loosens it up...
