    BMW E30, starter and power window issues

    Okay.....here's an odd one..

    Sometimes when I crank the engine, the starter won't engage....can here the solenoid click though....after a few attempts of "clicking" the ignition switch on and off....finally starts.

    Oddly though....this has been intermittent. But.....it also is messing with the Power Windows. They now no longer work, but at times they come back on, then go off. Also....sometimes the power window switch lights stay on with the key off.....this has also been intermittent.

    I remember a while back when I replaced the starter I connected the Black w / green strip wire that goes to the starter solenoid in on the wrong contact. Did basically the same thing......no start....and no power windows. Once I switched it the right contact on the solenoid, everything was fine.

    Anyone experienced this? If so, what was the remedy?

    Can't figure out on the wiring diagrams the true relationship of the Black w / green stripe wire on the solenoid to how it affects the power windows.

    Hi, you could have a faulty ignition switch. Test terminal 50 (black / yellow wire) at starter motor when it doesn't crank. You should have 12 Volts whilst someone is holding the key in start position. Cheers

    if youve got the early diag connector jumpering pin 11 and 14 should manually crank the starter

    My E30 wont start aswell... like it cranks but wont kick over...

    There is this clicking sound so I think its the starter motor...

    Anyways is the startermotor located like near the fuel filter ( in engine) for the M20 E30's?

    And does it have a black cover on it?

    yeah passenger side, big cylinder with small cylinder above it or below it.

    what do you mean it cranks but it doesnt kick over?
