V8 two wheel drive automatic 107,000 miles.

Warm air will only blow out of the passenger side vents when adjusted to front vents, floor vents when adjusted to floor, and defrost when adjusted to defrost with both levers to full heat. Cold air blows out the driver side vents.

You will need to replace the left side temperature door actuator. It is located on the bottom side of the HVAC box above the transmission hump.
