Hello everyone!

I have the following problem with my car. It only blows (very!) hot air from all of the vents in every AC setting. I have a car with a NAV unit.

There seem to be some threads regarding this problem, but there seems to be something specific to mine. The faster I drive, the cooler the air becomes. When I stand, it's crazy hot, when going 180-220 it becomes normal, over 220 it's really cold.

Oh, and the vents seem to blow full speed, when on auto setting.

Any ideas what it could be?

Thank you all in advance.

EDIT:

So, I tried it out again. The car was blowing hot air only. After going 220 and more, it started blowing proper temperature on the drivers side (LHD) but still warm air on the right. Even after stopping, the temperature in my side was normal, but the problem persisted on the right from all vents.

After some pause, the car was off for 10 minutes, it remained like this: left side ok, right side hot.

 

DCCV and the CCM. Just went through a similar problem on my car. Make sure you repair both.
