Wipers won't turn off reliably?

Replace the wiper motor assembley. The circuitry is messed up.

There's normally an autopark switch that tells the wipers to stop when they're fully down, maybe this has frozen, or perhaps there's a wedge of snow that's preventing the wipers from parking properly, or some plastic gears in the wiper gearbox have gotten shredded, in which case you'll need to fork out on a new motor and gearbox ($$!)

An Alfa with an electric powered concern? Mmmmmm. i'm specific interior the handbook there's a website asserting, 'your Alfa might have distinctive electric powered issues yet do no longer concern, it rather is thoroughly widely used'. they're a tremendous automobile to force, (maximum fashions) ooze character, tremendous interiors, a automobile with soul yet they are surprising whilst it contains reliability quite electric powered issues, the sellers get a coarse holiday too whilst it contains comments. attempt an independant automobile electrician because it ought to purely be a quick on the cables or fusebox, in case you purchased it 2d hand there might have been somebody fidgeting with the electrics.

Sounds like the motor got screwed up, or the connection was damaged.

The fuse has nothing to do with it. If it were the fuse, they wouldnt be working at all.

Its not a costly (or difficult) repair. Just take it in to the shop.

from what i've heard it sounds like you broke the switch or the wiper strippers i believe its called. mine have been acting crazy too ever since the cold freezing weather. i've been told i have to get a new wiper motor/relay.

sounds like your wiper switch went out.

Check your wiper motor, and your wiring.

You probably need to change the fuse
