Just replaced the battery on my car tonight, the N/S headlight wiper had stopped working when we had the ridiculously low temperatures a few weeks back, I put it down to something freezing up. Tonight, after connecting the new battery, the wiper did a full up and down sweep, then back up again. So now it's currently stuck in the upright position. I think it works with the windscreen washers, but looks like it's either parking at the up position, or possibly not working again.

Does anyone know if they can be reset so they're both back in the parked position?

You have to pull a fuse (forget which one) located behing glove box, it will then reset.
