The shop replaced the 8A fuse with a larger fuse and apparently everything works as it should. If the headlight wipers only work with a larger fused - does this indicate a damaged relay? Or perhaps the wiper motors are too old/worn? I am worried that the larger fuse will not protect some vital and expensive electronics.

Your comments will be appreciated as I really have no idea what risks I have with this larger fuse in place.

Thanks,
Paul
