I call it the einviper.... But anyway when I turn the wipers off the arm swings back left but stops with about 6 inches to go. IT will not go all the way home under the bonnet where it belongs. As such I have failed my annual inspection :(

I've read a few articles out there on it but can't come up with anything conclusive. Some folks talked about cleaning contacts on a very expensive relay but they fail to mention where that relay is. Any thoughts on how I should proceed?

Regards.

No I don't think it goes too far. I will double check that tonight though.

Yeah I guess I should jsut start taking things apart and having a good look.

So this is pretty crazy. I can't for the life of me imagine how this could have happened. I've had this car for about 10 years now and have done most of the work on this car and have never gotten into the wiper assembly before. I've also driven the car in the rain countless times here on the east coast U.S. with no problems. Anyway I get the assembly out and put it on my work bench and then realize... Huh? WTF? Really?????

The three mountin bolts for the wiper motor are simply gone, they are not there. So all this time this motor was not bolted or somehow magically the three bolts disappeared. How in the world could this thing have functioned for so long without tearing itself up? You can see there is some damage to the frame assembly and one of the bolt holes in the motor is blown out the side.

I'm at a loss for words. Uh yeah, there's yer problem.

Does anyone know what size bolts those should be? Need to run to the hardware store today.



Here is one of the bolt holes enlarged and ovaled out.

Yup 6mm, thanks. Yeah it's the oddest thing for sure.
