So this morning I started my car and tossed on the defroster to get rid of the ice on the windshield from this weekend. Most of the ice was melted and was water droplets so I flick on my wipers, well it turned out that the passenger wiper was frozen to the windshield still. I tried to shut them off but it was too late, the drivers side went but the passenger stayed in place. I got to work and chipped the ice away from the wiper and now it only moves about 3 inches. Am I looking at a new motor assembly or did I just strip a gear that is easily replaceable?
