Only passenger side blows hot air

[sabikeuk]

Only passenger side blows hot air, drivers side blows only cold air, tried to put temp to high but no change.

Any idea guys?

The yellow lever.

Nevo, I read a few your posts about this problem, but I don't understand what you mean by yellow lever? Where is it? Is it possible to repair ?

Thank you,
Dan

remove the glovebox and you will see the coloured arms attached to motors at one end and the flaps at the other.
They can stick, when you can see the arms operate the aircon controls and see if the levers move.

As kite says, but I believe its your drivers side so up by the clutch pedal remove the trim to gain access the levers,you will see the motors attached to the levers,I think your problem is the yellow one,disconnect the motor,then push the lever by hand,see if you get heat,the report back,its ok to run without the motors.

Ok I will let a go. So I don't need to disassemble it and lubricate? Just to push lever by hand , that's it? How can I run without motors?

[nevo]

It will need lubricating just make sure its the right one.(providing the little motors ok).
