Thanks jacekpk for the really good explanation of how to reach the actuator!
I got the same problem with my HVAC, it was not possible to get air blowing “on the socks”:) and it was constantly blowing through the front vents.
Readout of codes saying “actuator jammed” and calibration did not solve the issue.
I removed the actuator according to your instructions. (Removed minus from battery when I removed airbag). The thing was, when I connected the battery and tried the actuator only hanging in the cable, it worked/turned. I then assembled it again and it worked. Flaps moved and everything worked. I did not check the fault codes at this time.
The day after I did a readout and I find that I had a new fault code saying the front actuator was not calibrated (basic setting not performed). I did the calibration (pushing front went and AC for 3 seconds). Then everything stopped working again… Code actuator jammed.
I wonder what the fault is. Maybe I shall try to change the actuator and try again?
When I moved the flaps manually the feeling was that they were moving easily.
Any advices?
