Hi, I have a rare M Roadster & the screen washers are not working, is there a fuse I could try or is it likely to be the washer motor ? Would appreciate your views !
There seems to be three fuses that affect the washer/wiper circuits
F3 F36. and F44
if all these are ok then make sure you are getting 12v at the pump. That should eliminate the switch.
Also make sure the reservoir is clean as they do get gunky at times and clog up the motor
And check to see that the pipes and nozzles are clear.
Your washer check power at pump with a multimeter or test lamp if the wipers ok and pump not working fair chance its the pump.
Looking at the way the wiring set up pump is powered by fuse 44 directly but it splits after the fuse into 2 then goes to pump the other hoes to wash wipe module.
