2008 Grand Marquis heater blows only cold air Does anyone know how to fix this
problem before I go to a dealer and get ripped off?
eather the control panell is bad or the thermostat is stuck open not letting the engine heat up to operating temp.or thermo has been removed.
can be many different things the hvac blend door could be broken or the atuator is not working, or the head could be at fault.
more often than not it is the panel or the blender. but also check the heater core it might be blocked
