Wiper over-ride switch

So my 200Tdi 90 has an intermittant fault with the wipers, Quite often when going up or down main beam/dipped the wipers will give one wipe, pain in the proverbial and I've been replacing/checking earths all over the place, and now given up. This has been going on for something like 3 years, and every time I think I've fixed it it comes back. Am going to have the body off next year (been saying that for a while as well) so will redo a lot of the wiring then.
As a temporary fix what is wrong with me taking the fuse out (15amp IIRC) and pushing a crimped blade teminal into the live when switched side, a short length of cable with a spade to the now loose fuse, another spade from this fuse to a switch on the dash and return from this switch with a crimped blade terminal into the 2nd slot in the original fuse location. I know this is a bit Heath Robinson but it will do for the time being and the switch I put in will do for something else when I do her up.
Meant to say that in normal use the add on swich will be off, if I want wipers then both this and the stalk switch would be operated. Does that all make sense? Sounds like a logical and safe bodge to me. Funny what you think about when your fishing sometimes.

It'll work, and won't be any more weird that most ageing Landies. But you will be held to account for your promise to re-wire correctly in the near future.

Ta muchly for that.

Near future could be measured in cosmic terms though.

have you tried replacing either the indicator or wiper stalks? I had a similar problem a few years ago and replaced the indicator/horn/dip stalk assembly on my 300tdi and it went away.

I guess I may have just wiggled a shorting wire out if the way or something but hey ho!

Your solution is hurting my OCD! I think it would be quicker to take the wiper switch covers off and just replace the switch.
