Working perfectly normal until last weekend, I went to turn off my front wipers and instead of parking down low, they come to a stop at the opposite end of the cycle - both wipers stay up at each end of the windshield. Otherwise they work normally; both high and low speeds and intermittent operations are fine. It's just that they no longer drop down below the hood when turned off.

Is there a switch that could have moved? Is it internal to the wiper motor itself?

This is on a 2003 Montana - same as the Venture but there isn't much action over on the Pontiac forum so I thought I'd ask here.

Thanks for any advice.

 

The Wiper Control box controls the parking. Its a black box by the wiper motor. The same box is on the Venture.

 

Okay, it's working now. Pulling off the long plastic cover over the mechanism, I sprayed lube (fluid film) over the rotating assembly directly over the wiper motor, tapped it a couple of times with a block of wood, (didn't want to hurt anything with a hammer) and it started functioning as it should. I'd read about this elsewhere, gave it a try and was happy to see it succeed.
