Dear 964 companions,
Perhaps you could help me out on the following. My climatcontrol blower does not seem to work properly.
If I put the climatcontrol on a low temperature like 18 degrees celsius and i put the blower on stage 4 it goes full blast.
However if I put the temperature on 21 degrees celsius or higher, on stage 4 it does not seem to work at all.

Any ideas or suggestions?

Regards, Maverick964

Thank you Dick964!
Yes the AC system itself is in perfect condition. FYI we adapted the filling plugs and filled it up with R432a
Have a nice weekend!

You have a problem with the rear fan. The CCU is supervising all fans, and will shut down the two main front blowers when a problem occurs with the rear fan.
The rear fan shall start when heated air is needed to the cabin. Check rear fan motor, fuse, relay and low speed resistor.
See my DIY page for details and how to test the fan.
Cheers,
Tore
