I want to remove the ones out of my S10 and regrease the motor bearings or the gears inside them if they have gears........ I'm betting it's a nasty to get to them as in your van. The motors turn slow when the weather is cool, and being a '93, I'll bet that old grease is pretty thick on the bearing surfaces. I figure regreasing them will make em last longer.Well, Friday I put new window motors in both front doors of my work van. What a PITA!
