Rear window pump not working.

[ML320MN]

I read here that there is a joint fuse/relay for the rear window pump but cannot find the location again. Does anyone know where the fuse is located?

Thanks ML

From what I recall the Ml had two washer pumps in the reservoir

if your front windshield washer works, then it's the pump. Look at the reservoir and you will see 2 cylindrical pump coming out of it, one goes to the rear and one goes to the front. You just need to empty the reservoir and replace the defective unit.
