no wipers

[mark740_5]

problems with windscreen wipers as i they don't work at all,pulled the fuse board out and there is power to the relay,the relay clicks away as normal on intermittent,checked the feed on the block connector with ign off=no feed.ign on=12v on post 4,wiper stalk to on speed 1=no feed apart from 4.
wiper on speed 2=12v on post 4&5,stalk on speed 3=12v on 3&4.but absolutely nothing moves the motor

Does the full beam flasher work. (same fuse on mine).

[mark740_5]

thats funny, it didnt flash but i changed the fuse and now the flasher works but still not the wipers

Hmm, i'm not sure then.
I would start with the easy bits. The park switch is reknown for water ingress, rusty contacts and "unusual" performance of the wipers, although something should be happening.

If you remove the retaining bracket, and lift/twist the motor, you will see the three cables coming in to the motor. Do you have power to this point? If so, then it sounds like the motor its self. Its not out of the question for the brushes to be knackered. These can be checked by dismantling the motor. BUT be careful with the tiny bearing that will jump out across the garage floor to be lost i now have some spare if this happens.

I would also check teh wiring at the other side of the park switch. There are 5 0r 6 wires IIRC going into the plug housing. Make sure that each of them, especially the back one, is making correct contact with the park switch.

Good luck

I was playing with my park switch on Sunday - as you do!

Thought I'd done something stupid....had no wipe at all! So connected the plug to the wiper with the park switch NOT mounted into the mouter. Lifted the blades from the screen and confirmed the motor would actuallly work....It did.

So - just a case of switching off the ignition with the arms in a vertical position then remounting the park switch and everything OK.

so how can i test the motor with out the park switch connected as it fell apart when i took it out

[mark740_5]

so what else was the wiper motor fitted to, so its cheaper than TVRs £200

A new park switch is less than a tenner, and you will need one whether the motor works or not... i'd buy one and see

[mark740_5]

fitted new park switch now ant they still dont work is this a motor problem now?
i have 12v on terminal 4 but still no wipers any more ideas

Might be worth testing the resistance across the motor windings. That may indicate a burnt out motor or a loose wire..
