the problem may be a blown fuse in position 7 or 8 in the fuse box under the bonnet next to the battery, it is on the same circuit as the windsreen washers and so with the bad weather we 've been having i have seen alot of the zafiras with the same problem.if the fuses are okay check the micro switch in the handle as they also suffer from this as well.
i hope this helps,craig.
