This morning the weather here in CT was lousy. It snowed last night and then it turned to rain this morning for the morning commute to work. As I am cruising along at 60 mph, the wiper arm, set a the low speed, started to move at a slower pace. Then I started to get a whiff of a burnt electrical smell. I clicked the wiper down to intermittent and the smell started to subside. Then it flat out stopped in the rest position. It's pouring out, in rush hour traffic, I am going 60 and I can't see hardly a damn thing.

A little backround though, as this smell I mentioned and slow speed has happened once before. Last winter my wife was driving the car and the wiper slowed to a crawl and she got this burning electrical smell. I went out to the car at that time and noticed that there was a large build up of ice and snow, seemingly impeiding the movement of the wiper arm. I cleared it out, but the wiperarm was still slow. The next morning, it was working fine.

Back to this morning's issue, there was no ice or snow build up on the windshield or at the bottom of the windshield.

I did not get a chance to check on the fuses, but, how difficult is it to change out one of these wiper motors?
