Windscreen wiper problem

[kamer]

I have a Nissan Micra K12,2003. Lately it developed a fault which front screen wiper starts as soon as I start the engine. This happens when there is moisture around. It runs 5 to 7 minutes and than stopes. It does not do this in dry weather. I disconnected the moisture sensor but still does it.
I'll appreciate any suggestion/ideas. thanks in advance.

Moisture in air bridging electrical connection somewhere?

Goto town with wd40 , that would be my first port of call

If the wipers are switched off when this happens, I’d look at the self park mechanism- that is live all of the time.

Thanks John. Could you explain a bit more please? I don't know where the self park mechanism is. I took out pump fuse but it has no effect. When the engine warms up everything is normal.

Thanks, where are these connections? Any idea ?

You'll notice when you turn the wipers off at the stalk, they move to the self park position (not when you turn the ignition off though)......this is because there is a live feed to the wiper motor and particularly the self park switches within.
Anyway, the Micra has a 'Body Control Module' (BCM) which controls such things like this - nothing is simple! I'd do some googling to see where it is, and then unplug its connections for a few minutes - much the same as disconnecting the battery for a while - although this will lose you the radio code.
Firms such as BBA- Reman or ecutesting.co.uk may be able to help.

Thanks again John. I'll try see what happens.
