Thanks to all who took time to reply. Well, I wouldn't mind replacing the motor with an electric one, but I haven't converted the system over to 12v yet. I did spray the windshield w/water last night to see if it would help, and it did not. Before I did all this, I took the motor out, and inspected, cleaned it up, and put some new lithium grease in it. The paddle looked good. Tonight, I took out the transmission arms, and soaked them down with lube so they would for sure be free. They seem to be. I put them back in the truck, fired it up, and still the wipers try to work, but they just can't seem to. I guess I will get a rebuilt motor from Jim Carter and try that. I probably won't drive the truck when it rains, but I have to get the wipers working so the truck will pass the safety inspection here, so I can tag it for the road.
Thanks again,
KT
