Q: Heat blowing on driver side but not passenger

asked by on December 13, 2016

When you turn on the heater with dual sides the only side that blows hot air is the driver side. The passenger-side blows air but it is extremely cold.

My car has 65000 miles.
My car has an automatic transmission.

The most common cause is the temperature blend door actuator for the passenger side is bad and needs replaced.
