04 Silverado. My wipers were intermittent, you turn them on, and they would stop in the middle of the windshield, but now they don't work at all. Wipers or washers don't work at all now. How does this system work on a chevy? Is there a delay control module? I'm leaning twards a switch due to the last time they stopped in the middle of the windshield, they turned back on when I hit my left turn signal. Any info would be nice before tearing into her. thanks!
