Mitsubishi Repair: 2003 mitshubishi galant, nothing but air, heater core

Question
when i turn my control to heat, nothing but air comes out...the control knob doesn't click when i turn it..it appears to be loose. sometimes i can smell a funny smell when i turn the knob to the heat area. What could be wrong

Answer
Annie,
You may have a bad HVAC switch, which controls the flow of coolant into your heater core.  If the coolant is not flowing properly through the heater core, you may not get as much heat as expected.  I would recommend having a mechanic inspect the heater core and the control switch.
Good luck!
