my toyota sienna 2005 has heating problem on passanger side is fresh air and driver side is hot
i change thermostat ,antifreezer,nothing happen,i put new radiator,i change the heater
Sounds like a bad controller on the dash. The thing with the knobs and buttons. Try getting the unit from a junk yard.
is it leaking antifreeze on that side if it is it could be your heater core
s not leaking, everything is fine,except the heater from passanger side and rear
am going to see how much is the knob in the junk yard,thank you for you comment..everythink idea help
hi..i try already with a new knob controller and has same problem..can somebody help me
I have the same problem on 2004 Toyota Sienna. The difference is that the driver side does not heat up, but passenger side is heated in the winter. In the Summer, it is the opposite. The air condition doesn't work (hot air) on the driver side, but works with the passenger side. It seems that the back follows the driver side.
