Re: Wiper relay
Have a look at the other threads on here about the wipers.
Mine got worse and worse, blowing fuses and not parking. I looked for the relay, was told there was not one, pulled out the motor and dismantled. There are problems with grease getting onto the copper contact area. Cleaning this can help. The contact area can wear through. Need a replacement. The contacts can lift off from the contact area. Bend back down. Or, as in my case, the whole thing is clapped out and you buy a new one on the web for about £100.
It is pretty easy to change. Take note of where the wiper linkages are sitting before taking them off. They can be a bugger to get back in the same place.
If you get really stuck let me know, I am not far away from you.
