Heat/AC Question
**I couldn't find a board specifically for this question so if I'm in the wrong board please move this post**
The weather has been getting a little bit colder so I've had to fire up the defrost/heater. I've noticed that no matter where I put the selector(VENT, BI-LEV, HEATER, DEFOG), it does not affect the air coming out. It seems like the air is only coming out of the vents and just a little bit through the defroster ducts. Again, it does matter which option I select. The temperature control works just fine. Is there anything I can do to get my heating system to cooperate? Thanks.

You either have insufficient vacuum to operate the heater door servos, or something fell in there and is jamming the works.
Or, something is corroded/frozen in place.
I'll bet vacuum, though.
