Climate controll.

[Alex-svx]

I have take a diagnostic test on my clima controll and get the code 34.
When i choose Defrost the air flow goes on window and when i choose auto or vent the air flow only goes on window and foot. It will be Nice to get the hole cupe to get cooled down not just the feet.

The code is 34 Mode door motor faulty engine .
And when i try to look on the part catalog i can only fine:
Motor-acturator mode part 72041PA000
Motor-acturator mix par 72063PA000

Is the some of these that i have to change? And how is it hard to get this fixed?
