the wipers on my 92 mayfair will only work on one speed and not on its fastest setting, they also do not park.

i thought as the wipers do work albeit only on one setting that the motor must be functioning so any suggestions what it might be?

Matt,

Hmm, park is actually a part of the motor but as they only work on one speed could be the motor or wiper stalk

There is like a plate inside the motor assemble which does the self park thing, so would guess you either have a wire loose or need a knew one of these boards.

There is a park switch on the motor. These are easy to change and will more than likely cure your problem.

The park switch operates on the lower speed wiring. The supply (green wire) goes to the motor, The low speed operates as a bypass for the park switch to keep the motor supplied when the park switch is open. Since it sounds like only the bypass bit is working look at the green wire at the motor, it should be live with the ignition on. Also try removing the park switch, it also earths the motor when it opens, to stop it dead. If it's stuck open it will cause a permanent short.

Your Mini is recent enough to have a fuse for the wiper motor, so it should be wired as follows:

Black - earth, obviously ok as motor runs
Light green-orange - live feed from fuse when ignition is on, used for parking
Blue-light green
Brown-light green
Red-light green all from switch

I can't confirm how the switch is wired, but Haynes suggests, from a rather poorly drawn diagram, that blue-light green has power applied in slow and fast positions, and in the fast position brown-light green additionally gets linked to red-light green.

The park switch is likely faulty, as has been said already, and can be changed easily, with some dismantling of the drive end of the motor. They are notoriously unreliable. Check that with ignition on, you have power on light green-orange for all positions of the wiper switch, and on blue-light green for fast and slow positions.

Thanks for the advice will have a look tomorrow!

So the wipers are working just like a Mk.1 then

[Ethel]

Blue-green is fast speed, red-green is slow speed.

So much for the clarity of the Haynes diagrams!
