2005 ext front wiper stopped working on continuous slow speed, but all other speeds work continuous fast and all intermittent speeds. also front washer stopped working what can cause this? Thanks for any advice.
The speed control is a circuit board that's built into the motor housing. The often get wet inside and corrode. Its not replaceable by itself. The entire wiper motor assembly and arms need to be replaced. The bad news is that its a little over $100 including the core charge. The good news is that as long as you have a wiper removal tool replacing it is a 15 minute job. I'm don't believe the washer pump is controlled by this board also, but I could be wrong about that.
Mine would work fine for a while, then just run non-stop no matter speed I chose, even off.
The washer pump is controlled by the circuit board, so that could be it, or it could be a bad pump, W/S Relay, or W/S fuse, both in the underhood fuse block.
Thanks Roadie. Given that, I'll bet on a bad motor/circuit board since his slow speed isn't working either. That said, fuses are easy to check and an easy fix.
