Help: Windscreen Wiper Problem.....

[Ritesh]

Hi,

Basically my windscreen wipers are only working on the fastest setting i.e. third click up

One-up and Two-up on the lever don't seem to be doing anything?

Could anybody shed some light on this for me....I am new to these E30s.

Am I correct in assuming that the third setting is on a different relay to the other slower speed settings?

I mean the fuse may have tripped, but because they are actually working on the quickest setting I am a bit confused. Could it be the switch?

I was driving...and they were working fine...and then suddenly stopped working.

Beats me!

Could be a faulty wiper stalk. Or maybe the mechanism needs a check-up ?

Click on the ARTICLES link at the top of this page, and go into Technical and have a read.

Cheers.

im articles there is a top idea of cleaning the motors, you'll find it.. worked a treat for. cleaned the grease off and tidied it up re-greased hey-presto...

there you go

That's what I did to them a few months back. Gave the motor a complete overhaul.

It's a complete mystery why they're not working now though... very strange.

[Ritesh]

Well I will do the same again I think...another overhaul.

However, if you gave it one only a few months back then I am a little bit concerned that it may be electrical.

Maybe a new motor?

They're not cheap I know that much; Approx Ԛ£100;

time to get friendly with your local salvage yard again lol

K10 wiper control module in the fusebox is the most likely culprit. Open it up and look for cracked solder joints.

I changed the relay too at the same time... the big black one.

Can only mean that the motor must be getting tired then I guess...

[Ritesh]

Okay...well if relay has been changed too, then i will assume it is simply the motor.

Off i go in seek of a motor!!

This could still be the wiper switch, so before you go random part changing, do some tests.
Pull the relay in the fusebox, and with a piece of wire, apply 12V+ from the battery, preferably via a fuse, to pins 53 and 53b, one at a time, and with another bit of wire, connect pin F1 to earth.
This should make the wipers work at normal speed and fast speed (can't remember if 53 or 53b is fast.).
If it only works on the fast speed, then the motor is probably dud (normal speed brush stuck or worn out), or there is a problem with it's plug and socket.
If it works on both speeds the problem is most likely the switch. Check by replacing the wiper relay, and earthing the black/red wire at the switch plug/socket.
If you go on a scrapyard search for a motor, then check for wear in the spindle. The RH drive E30 has the spindle positioned where it collects a lor of water and dirt, and wears badly.
On a couple of occassions I have replaced E30 motors with ones from either an Audi or VW (can't remember which), which are identical apart from the connector( so get the plug and a few inches of wire as well).
