Rear Wiper

[Rob Gibson]

Goes on ok but wont turn off .
Is this a wiper motor problem or something to do with the wiper control unit.
Has anyone else had this problem?

control unit is my guess.

did this just start happening? (did it work okay before)

When you click on the stalk to turn it off it does another couple wipes.
For years I thought it was broken.
Are you sure you are just not waiting long enough for it to turn off?

I have a problem when I turn my windshield wipers on that the rear sometimes goes on.

Once on you need to press it two times for it to shut off. So once you see it move push once let it cycle and then push it again and it shouldn't come on.

i used to get so mad i would just shut off the car whille i was driving to turn it off.

Thanks Guys I'll investigate further and try your idea Tyler.
I'm sure it used to be ok (but haven't had to use it often)
If it keeps up I'll exchange the control unit.

Before i new how to do it i used to shut my car off and turn it back on.

All the electrics are a bit of a mystery to a new user (me). The front wipers turn themselves off or pause while idling at the lights dont they? And start again when moving forward? And I still havent worked out the sequence for opening the sunroof to vent only, fully open , or one third open. I'm going to look now to see if I have OBC display. I do think however that a lot of the operating faults I have seen discussed here may not be faults at all given the care BMW put into their vehicles.

[aceyx]

correct; the wipers are speed controlled (the will operate at a lower speed when at a stop, then resume when the car is moving again).

with the sunroof closed, push the forward button (as if you're closing it from fully open) to vent. back, or "open" to close the vent. then normal operation for sliding open.


to see if you have OBC, push in the turn signal stalk. the display should change.

So I don't have OBC display.Thanks for sunroof tips.
