2016 r1200rt windshield issue

[BMWDetroit]

Here's one that has me stumped. 2016 r1200rt 70k miles. About 3k miles ago I noticed that my windshield has about 1/2 inch of slop when it is up 3/4 to full. Meaning it doesn't extend all the way. I have pulled everything about, cleaned and lubed everything, i.e. control arms, springs, brackets etc. I have noticed that the motor hesitates for a quick second about 3/4 up and that's when the slop starts. However, it does not do this without the weight of the windshield on. I have recalibrated with the GS-911 several times (with shield on) but it doesn't fix it.

Dealerships say they have not seen this problem. Has anyone else experienced this?

so, its winter time in Missouri and of course we need our wipers to work... well, not sure why this happens, but sometimes i can drive around and everything works fine.

Then other times, I will need the wipers to work and they wont... i have sprayed my windshield to clean it off and the wipers will not work... kind of a safety issue. sometimes, i will be using them and they do a few passes and stop out of no where.

In the summer, this doesnt happen at all. But now it does it in the winter... if i hit a bump just right, they will come back on. Sometimes, if i force them up a bit on the windshield, they will work again...


I need to check for a lose fuse, but in case that doesnt fix it, where else should i check. this is becoming very annoying and wondering if there is a lose wire or connection in a plug somewhere...

any thoughts or help are welcomed.
