FAQ
The button lights up, but the recirculation flap does not move. Is the switch at fault?
According to forum reports, in this case it is usually leaking vacuum actuators or the changeover valve, not the switch.
What connections and markings does the switch have?
6 round pins. Printed on it are the SWF diamond logo, 501.168 and the Mercedes star with 126 820 50 10.
Does the switch also fit the W124?
No. The W124 has a different A/C system. The W124 residual heat switch 124 820 11 10 (SWF 501.127) is also a different part.
