OK, John's idea reminds me how I once found a relay someone turned upside down. That's a great suggestion he's given, because at 15 degrees, you could probably pull that off without too much pain.

I think you would be pretty lucky to fix it that way, given it does not work in any position.

Should the relay not be the problem, here's how to trace it provided you are lucky enough to be able to work when it isn't:

1) You have a wagon. Check the rear wiper. It is on the same fuse. Let's say you found this post and you have a sedan. Toot the horn. Squirt the washers. Doing this proves the fuse isn't cracked and shrunk open.

2) Use a test light under the hood. Assuming the wiper still doesn't even grunt in any position, put it in fast forward and turn the key to KP-II. Check for voltage at the wiper motor plug. Your light should come on at the yellow and the green wires. If it comes on at the brown wire too, the wiper motor isn't getting the ground through its housing.

3) If you haven't found the loose/dirty connection yet, take the cover off of the gear case on the motor and check, using your test light, where power reaches. It could be simply the motor has short brushes, and you know what happens to the length of things in the cold.
