GLA heater flap reset

[colinallcars]

My daughter’s GLA 200 has a problem with the air distribution system, only a weak flow can be directed to the windscreen although the full blast demist seems to work. iCarsoft suggests a mechanical malfunction so I hoped a reset of the flaps might cure it but the usual ‘press demist and recirculate for 5 seconds’ doesn’t work. It has the basic aircon controls, not climate control. Any suggestions on how to perform a reset?

The obvious is to use STAR/Xentry to do the reset, after reading any error codes.

Indeed but I was rather hoping there was a button combination that had the same effect.

When I had an issue with the flaps on my S203 the two button combination only worked to a point and it needed STAR to fully reset the operation of every flap.

Have you checked that the cabin filter isn't blocked?

Yes, it’s a new one.

Try actuating blender flap via xentry and see if the motor moves. The flap could be seized. I've replaces a couple on r172 slk
