In my case for months I had no intermitent wiper function and I had to turn em off when they were down because once I turned the **** they stopped wherever they were at. I was just puttin off changing the motor and one day they worked just fine again. I don't know what the problem was or what changed.

 

I'm tellin ya bubba...it's the rain sensing wipers. You must have bought the upgraded blades at KaleCoAuto

 

Hell I gotta road sensitive truck, any time it sees a road comin at the end of the driveway it does all it can to keep off of it.

 

so I guess it didn't like the waxing you gave it eh?

 

It really thinks it's the boss now. I got news for it, it can squeel that water pump for the next 1000 miles, I aint changin it till I'm ready to. Or until I'm tired a hearin it.

 

or until it freezes up, starves your engine of water, and your pistons melt to the block.
