2006 Subaru B9 Tribeca Has anyone found out how to fix the cold air blowing out of the passenger side and hot on drivers side?

ALL ELSE WORKS
CAR DRIVES?, HEATER AND A/C WORKS OK?

Maybe you shut the heater off on the passenger side.

There is a switch that controls both drivers and passenger heaters. One might be off.

Chlorine in factory coolant has caused corrosion and damaged the heater core (there was a recall on this WWY-09 which my subaru dealer denied!) flushing wont help. Heater core needs to be replaced.

I just spent five hours replacing the passenger side bulb because I did not know to leave the spring alone. I then replaced the bulb and when I went to check the headlight, the drivers side blew out. 5 minutes job turned into five hours.

I just encountered the same problem with my 2007 Tribeca. Any info you've found as to what the problem is/was? Thank you!!

Most of the time the dash has to come out to access the actuators on the heater box.

you have a shutter no functioning
