I have the same issue. Check the Vaccume lines. I'll repost what the other guys said

I haven't tried this but give it a shot. See if the Vaccume isn't pushing properly for the heater control to work.

Or look under the dash and see if any linkages have come undone

I had the same issue. Check the vacuum line that goes through the firewall through the foam around the ac lines. Mine broke off just inside the foam. Lol make sure to cover your eyes when you throw it on vent.
