2008 Toyota Sienna XLE Limited - HEAT not working on Passenger Side


Asked by Sep 29, 2016 at 04:00 PM about the 2008 Toyota Sienna XLE Limited

Question type: Maintenance & Repair

I have a 2008 Toyota Sienna XLE Limited – I am the original owner and it
has close to 200k miles.  Yesterday when I turned the A/C to HIGH (heat),
only the Passenger Side blows heat. I turned the heat the whole way up,
and the Driver Side (left side vent by door and center left vent) only blows
Hot air.  The Passenger Side (center right vent and right vent by the door)
blows Cold air as in A/C air.  

I then switched the thermostat to LOW (a/c) and the Driver side blew ice
cold air.  The Passenger Side blew cold air, tho not as cold as the Driver

SUMMARY, the Passenger side temp is not adjusting when I change the
thermostat.  The Driver side is changing per the dialed in temp.  

Any thoughts or suggestions would be helpful.
