Re: 147 Wipers Horror
Have the wipres cut out completely or are they left struggling really badly? A few years back I had a problem with the wipers on an astra. When you turned them on, they'd just about manage to move a little and then stop dead. If you turned them off for a few seconds and back on, they'd do the same. I stripped it down and took the motor out and tested it, it was fine, put it back in and everything worked. I was confused at first but then realised that the earth connection from the motor was badly corroded where it screwed onto the body. Undoing the screw and refitting it caused some of the corroded metal to flake away and re-established the electrical connection. I gave the connector and screw a quick rub of emory paper and had no further trouble.
It could be something as simple as this. If it's the motor, e-bay is your friend, there's lots of alfa's being broken, most don't list all the parts but if you contact the seller, they'll put it up for you.
