My cabin ac directions (vent, dash, defrost, heat) have defaulted to the dash no matter what control is selected. The blower works fine. I wanted to check with you all first. Could it be.....
Satan
Fuse
Vacuum line popped off under the dash (I suspect this based on below)
other ??
I have never had any problems until just yesterday no recent changes.
I have noticed in the past that when I would switch from defrost to heat there would be a delay and then a pop as the door in the vent opened and hot air started to blow out by the floor.
Please help we are getting awesome late season ski conditions in New Mexico and I really need my defrost back.

Could be a vacuum line on the control unit. Could also be the little vacuum canister under the hood. Its on the passenger side right in front of the firewall.. I have seen a couple that have gotten old and cracked.

I would check to see if you have a disconnected vacuum line.

Thanks Craig and Caleb. This is just a new one to me now I know where to start. Hope I don't have to get into the dash.

yep, that's 98% likely your problem also.
also, if you ever have the problem where under load it goes from defrost to bilev, that little vacuum canister is probably bad. A new one fixed that problem on my car.
