Q: Issues with heating in the car

asked by on

Hi, my car has gone around 65,000 miles. It has issues with heating. There seems to be warm air blowing from the side vents. But, the center vents are blowing cold air. I looked at the coolant and filled it a bit. It seems fine and clean. I'm wandering why this is happening. Do you have any idea? Thank you.

The problem is in the air flow control in the evaporator case. The case has multiple actuators that control the air temperature and air flow to the different vents. One of these actuators that controls the air flow to the side vents needs to be replaced.

I would suggest having a qualified technician inspect your heating and AC system to confirm the diagnosis and recommend the best path to repair.
