my toyota sienna 2005 has heating problem on passanger side is fresh air and driver side is hot

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.

on my Toyota Sienna 2004 on the right, the heating does not work on the passenger side. that you can advise. thanks

my Toyota Sienna 2004 on the driver side i got heat but not on the passenger side

Anyone find a solution? I'm in The same boat....freezing.on the driver's side

I got a problem in my 2005 Toyota sienna I turn on the heater and one side is cold and the other side is hot , Can somebody help me with the answer

I had the same problem. It ended up being the heat actuator which I understand to be a little flap that regulates the cold air versus the hot air. Got that replaced and everything works great now. Well, except now the other side is on the blink.

The 05 sienna possibly others has 3 separate actuators on the passenger side ...bottom line if it blows cold it's the bottom actuator next to your left leg. Take off the panel on that side u will see.it that's it . The one up top is the cold air refresh one which is not it u can also look it up on YouTube that's how I found it
