Town Car 2007

My heater vents on the driver side blow hot air while all the others (passenger side and rear vents) blow cold air no matter what temp. it set. Does anyone know what the problem is?

If the car is still under warranty, take it to the dealership for diagnosis and repair. There is no need to diagnose the problem for the dealer, and in fact, they will undoubtedly ignore any diagnosis that you offer.

If the car is no longer under warranty, then you need to look at the blend doors in the HVAC system. One of more of the blend doors is likely stuck in the wrong position.

Are you sure that it is not just the driver blowing hot air?

Seriously, If it is not under warranty and you want some guidance, check at or
