Why does my car air vent blow cold on one side?

Why does my car air vent blow cold on one side?

This situation can be caused by a bad blend door (also called air mix) actuator, a broken or binding blend/air mix door, broken linkage to the blend/air mix door, or a faulty HVAC control head or wiring harness. Car makers used to rely on cables to change the position of the blend door to regulate the amount of heat.

Where does the a / C blow hot air and cold air?

Anyone else experience the A/C blowing hot air from the drivers side left vent and the left most center vent and cold air from passenger’s right most center vent and right vent? What model year? You may be low on refrigerant.

Is there cold air coming out of the passenger side?

WOW! part numbers 80321-shj-a02 and 80341-shj-a01. The “low freon” speculation…needs to be investigated. I suspect the cold air coming out of the passenger side is plenty cold, which would not be possible with a freon leak. Before bringing it into the shop, check out the driver’s side air mix motor.

Why does hot air blow from the driver’s side?

Sometimes it will get warm (but not as warm as the driver’s side) and sometimes it will simply stay cold while the driver’s side is hot. It seems like I must turn the dial back and forth a couple of times in order to the passenger’s side to blow hot air (but not get as hot as driver’s side).
