    Hi to all of you, my girlfriend has a 316 compact circa 2000, its been a great car for many years.
    I have one problem with it now though.
    The rear wiper/washer has stopped working, i thought it was a motor issue and have replaced the unit, but still no good.
    There appears to be 2 electrical connectors on the motor, a 2 pin lets say heavier connector that seems to be a power supplty to the motor, then a small 2 pin conncetor that is the switched connector. I am wondering if this switched connector is working correctly. Does anyone konw if this is straight off the wiper switch? and if so what voltages i should be seeing?
    Many thanks in advance.
    Simon

    have you checked the fuses. Nos. 3 and 44. Are the wire colours as follows:
    Plug 1
    Red/brown/yellow....12v constant from fuse No.3
    Brown.....earth

    Plug 2
    Violet black.....12v with ignition on from fuse 44
    Blue/green....earth (0v) switched when wiper switch moved to rear wipe/wash position.

    You may need to check where the wiring passes from the car body to the bootlid through a rubber gaitor up beside the hinge. Pull back the rubber gaitor and check for damaged wires.

    had the same problem with my 540i touring and my daughters 318i compact,it's the loom where it passes from rear door into car roof.very common problem and time consueming to repair.it is only a broken wire,if not visable stright away pull the loom out of the roof a few inches it will be there.good luck.(have now got the same problem with a 56 golf)

    Yes, those are the wire colours, thankyou.

    It seems i am seeing 12ish volts on both pins of plug 2. so tomorrow i need to investigate the possible chaffing issue. It all looks superficially good through the gaitor.
    I was suspecting the switch, but i will do more diagnosing in the light tomorrow. I might bypass the switch and manually feed 12v on plug 2 to check the integrity of my motor anyhow.
    Thanks again

    Remember the blue/green wire is the one from the switch and its a switched earth, not positive

    Done some checks today, disconnected the switch at the plug under the column and grounded the blue/green wire, everything works ok. Looks like the switch has gone faulty.
