P38 electrical problems

rryocon · Dec 2, 2010

Hi there,

I am having a problem with the off side headlight wiper motor, it seems to be stuck on, both the motor and the spray. I have removed the fuse and problem stopped but would like to fix it. Does anyone know this problem or do i need a new motor, etc..?
Also noticed briefly a fizzing noise from the under bonnet fuse box whils engine off, not affecting any electrics - both problems might be related?

Any help would be appreciated!

thanks, Rory

If you can hear fizzing, it's normally water that has got in, is corroding a connection and causing high resistance (and therefore heat).

I had this on my 1985 Astra GTE years ago, water was trickling down the bulkhead, straight into a wiring connector and fizzing quite loudly.

Take the under bonnet fusebox apart and have a good look inside it- it's a common item to suffer from water ingress.
