Hi Guys,
Just had my scoob a couple of months now and still reparing all the faulty bits on it! The rear wiper doesn't work still. The relay clicks and I THINK the electrical system is fine, having checked it with a meter. I've noticed when I cracked open the rear wiper gearbox though that the large nylon gear is missing a few teeth. If I'm right that gear is meant to do complete 360 revolutions to move the arm but if it's missing all those teeth it won't mesh and therefore will stop halfway round. I think then that I'll need to replace the gear - but I'd imagine it will be impossible to get a replacement and it looks at first glance to be a nightmare to get out as well. The rest of the motor and gears are in great condition and my local scrapyard charges something like £30 for a s/h unit which is far too steep. Any suggestions please?
Off work today so please get back to me and I'll get it sorted while I can!
Cheers

 

Im almost 100% certain that a replacement is the only way to go. Parts would be a mare to find and probably don't exist in this country.

Unless you can source one with, say, a busted motor, you're left with a s/h one.
Try e-bay or breakers.
