    Odd E30 Wiper Motor Electrical Issues - halp

    Hey R3V-

    I have followed jlevie's wiper motor diagnosis procedure multiple times and poured over ETMs, but still have an electrical issue has plagued my '89 325iS since purchase.

    The wiper motor intermittently loses power. When testing this, if I remove/install the wiper relay, I temporarily get power back at the wiper motor (confirmed via multimeter).

    The wiper relay (and several others I tested) are good. Switch tests out good at relay pins in fuse box, but have also tried several spares to no avail.

    I thought maybe the wiper stalk g201 ground (steering column) was no good so I relocated it to the g200, which did nothing.

    Occasionally with the motor plugged in and running on low speed it'll "click out" like a glitch and softly engage the horn.

    Any ideas?

    Clock spring maybe or a short some where in the steering wheel assembly.

      I've already relocated the steering column ground in the event it wasn't grounding properly there :/
