    Hello,

    I've got a 2009 T800 that's giving me some issues. The wipers will only run on high setting and I'm getting no power to the Window Washer either. I have checked every single fuse, put a new Wiper motor on, and tried two new relays,and changed the multi-function switch but I still have only wipers on high speed.

    This has me thinking it might be an issue with the wiper control module but before I sink any more time into this I figured I'd see if anybody else can help out.

    Also, if anybody could point me in the direction of where the wiper control module is located and how I can test it that would also be appreciated.

    Thanks for checking out my thread!

    This might help, the control module is usually found behind dash on right side of steer column on bottom sill plate.

    Check both relays and all fuses.
