Is there any spare 10A fuses in the fuse box that I could use as my window wiper fuse (15) blew, think it was because of frozen washer fluid! Didn't have time to get to a halfords/garage and need the car early morning!

How about fuse 13 for the reversing light, two up from the one that's bust? Could probably do without that for a day?

Exactly the same happened to me on monday. As wino said, reverse lights is the best option

Thanks guys, will do just now till I get to halfords tomorrow!
