She's a contrary wotsit!

My 90 that is.
Wipers have been behaving erratically since I got her, the intermittent setting paused where it felt like it and I had to turn them off at the right place or they halt half way up the windscreen. Then a couple of weeks ago the intermittent stopped altogether, same as "on".
On saturday afternoon the wipers packed up during a local monsoon, replacing the fuse sorted it. The fuse went again that evening, but the replacement popped straight away, as did the next one and the wipers weren't even turned on!
Being the eternal optimist I tried again yesterday morning and the fuse held and continues to do so.
Reckon I've got a couple of issues. The park switch for the intermittent (at least) and maybe the mech is getting stiff causing the motor to pull excess amps? The fuses blowing in sequence made me think I had a short, but then it works again now - hence contrary wotsit..

Just wondered if anybody else had similar issues in the past..

Certainly sounds like problems with the park switch to start with.
Wipers are designed to work in water, that's their job, but water can cause all sorts of untold chaos if it gets into where it's not supposed to be.
Check for water damage and corrosion in the motor, gearbox unit and drive system. Check for water ingress to the electrical equipment too.

Thanks, I'll get one on order and check out the rest when I'm in there. Come to think of it, we did go puddle hunting after the heavy rain..
Cheers.

Had the same kind of problem with wiper parking position on a RR along with other electrical gremlins !
when i fitted a new ign switch the wipers started too park correctly and most of the other problems vanished

My wipers have never worked 'well'. They work enough, but not as they should .. normal wipe is a bit stuttery, fast wipe is smooth but slow, intermittent you have to press the lever down and forward to make contact .. One day I'll maybe take the switch and the system apart, but while they actually work, there's other things to do ..

Very occasionally, with a full battery and a dry day (What use is that?) they will work as they should ...

I've ordered the park switch from LR Direct, it's so cheap and easy it has to be worth a go and I can take look at the motor while I'm at it.
The relay looks pretty straight forward too, though not so cheap.
Thanks everyone
