I have the same problem, after some research I found that one of three is the problem, the Compressor, the Altenator, or the Control Unit. - mustafatel
The heating, ventilation and AC (HVAC) heater box is susceptible to mildew buildup. This can result in a musty odor from the HVAC system, most noticeable when the system is first turned on.
The heater case for the center vents can crack near the stop sensors. If the stops break, the control motor will not know when to stop and will run continuously.
