Q: Car help

asked by on

My lights went out on both sides of my heater modular and my blower don't work right what would that be

My car has 140000 miles.
My car has an automatic transmission.

A few different components can cause the vehicle to have a heater and blower motor to not work right. This would most likely lead to a failing AC control unit, a mode door, blend door, blower motor, or low refrigerant. If you want to have this looked at, a qualified technician, such as one from YourMechanic, will be able to diagnose your electrical system and perform any repairs required.
