2007 Sienna XLE heating problems
I purchased my Sienna new in 2007 with dual A/C control for driver and passenger. When I put both controls on "HI" the air on the driver's side come out hot, but the air on the passenger's side come out very cold. This happens at all times of the day. I live in Southeast Louisiana so we don't use the heater a lot. Any ideas what could be causing this?
