Wiper

Today as it was raining....guess what....my intermittent wipe went to being in normal wipe mode. Is this a relay thing ??

Ah ha ! Mine's been doing that intermittently for a couple of months. However, with mine, when it starts doing that you can't even turn them off

It's likely to be related to the parking switch somehow. There is a permanent feed to your wiper motor so that, if you turn off the wipers mid stroke they can continue (powered by this feed) until the parking switch interrupts it.

Originally I dismantled my motor and cleaned everything. Although worn, the brushes seemed to have a fair bit of life in them. On re-assembling the motor, all worked well for a few weeks until it started playing up again

This time, I noticed that the small arrow on the motor body wasn't quite lined up with the mark on the top part of the motor. This could allow some misalignment of the armature in relation to the brushes. I slackened the two long through bolts and re-aligned it and it all worked ok......for a few weeks.

Finally, dismantled and cleaned again and this time it's been ok.

The only thing I haven't done is the most obvious - slacken the two (very inaccessible ) screws on the parking switch and move it slightly. As mine works ok at times I didn't think that was the problem, but who knows ?

Good luck Malc.

I had a non stopping wiper which, as Julian suggests, was traced to loose retaining screws on the parking switch.

Thanks guys...the wiper works super in the normal mode, and did work in the intermittent mode until today. If the relay was bad would the wiper work at all, or go into normal wipe mode.

The relay pulses a live and the parking switch break's it. So if the relay does not work it wont pulse a live in the intermittent switch position. Graham

So....as l had a relay from the other car l changed it out. And as Graham said, no change.....dammmmm. So is it in the wiper motor l need to look now ?

Before you start ripping things apart, when you switch to intermittent does it not work at all? when you are normal mode 1&2 does it park when you switch off . Give us a clearer picture of everything that happens. Graham
