well i had stuck wipers the other day, i leave them 1/2 way swept up the windsheild and under the drivers side i have a 2'x2' rubber-backed carpet mat. then when i leave early in the morning, i have a big clear square to see out from, also works good when there is freezing rain. wen to go to work the other morning and the wipers stayed where i parked them, tried helping them out by grabbing them by hand but they wouldnt budge. i could see the volt guage dip every so often, so i knew they were trying to work.the truck hadnt been driven for a few days, we had a real fine snow, then freezing rain, then more snow. the cowl area where the wiper linkage is was filled up with slush, it melted a little and refroze. i heated up some winshield washer fluid and poured into the cowl. thawed it out and works fine now.
