ABS light on, wiper & washer not working

[jnes]

Okay folks. Known problems are listed in topic.

First noticed that the high beam lights do not work when pulling multifunction switch. High beam works when operating normal (pushing the switch) Then ABS light came on and snow chain button (ASR) at center console were illuminated. Today when driving in rain find out that wiper is not working, neither washer.

I've searched that in pedestrian W124 high beam, wiper & washer not working can be caused by OVP relay but our cars don't have that.. BM failure ?

Any ideas where to start? Could these all related together? Sounds really weird. I haven't pulled codes yet out from the car but will do. Has anyone else faced similar issue?

Thanks

Regards,

The high beam on the 036 works when pulling the multifunction switch, with the key on... not with key off. Check that first.

There won't be codes for these issues because they are not powertrain related. Check the fuses for the wiper/washer, AND the relay for the wiper/washer also.

Next step is to trace the schematics in the FSM/ETM. Start at printed page 159, PDF page 185 (of 277). There's not much in the circuit besides the combo switch and combo relay:

I tested all the possible combinations. I'm still wondering how the high beam will work normal (press the multifunction switch, Or at least high beam indicator light up (blue light in instrument cluster)) but not when "flashing" high beam by pulling it. As far as I understand relay should be ok because lights work.

Fuses seems ok, just ordered new fuse box and will replace all fuses to new. Maybe I'll try also new relay.

Thanks Dave for the manual
