LMM: Windshield Wipers Quit Working

[Duramaxin]

I have a 2009 lmm now.
So I have been trying to find a fix for this for a month now. I went out of town for a week and when I came back my windshield wipers will not work at all. I test the motor by running power and ground directly to it but when I have the system all hooked up like it is suppose to it doesn't work. I check the windshield wiper fuse and it is fine. I also replaced the whole under the hood fuse block because I was told the windshield wiper relay was built into the fuse junction block. I have read two forum post where people with lmm trucks have the exact same issue but they never put what the fix was.

I am just trying to avoid going to the dealership and paying an arm an a leg to get it fixed. The only things I can think of that it could be now is a bcm issue which i find highly unlikely, a ground issue, or a multi-function switch issue on the steering column.

Has anyone ran into this and have a fix????? I need help bad

I'd start with a multi function switch. Not bad on
To change and can always return it if that's not the problem. Motor tested good I assume?

Ya I tested the motor and it tested good. Is it common for the multi-function switch to go bad? The washer spray, turn signal, and hi beams all work on the switch. And when I turn the windshield wiper on the headlights turn on but nothing else happens.
