Having problems with your Chevrolet S 10 ?
Ac comes out heat vent
\015 Ac does not come out of vents on dash. But comes out of heat vent under dash.\015
I would say the blend door is stuck or something happened to the selector on the dash. The system uses engine vac to move the blend door and direct air flow. If the vac source fails, the system is supposed to default to the defroster position.
