I'm at my wit's end! I can't get the driver side wiper to stop chattering. I've tried cleaning the windshield, and I mean cleaning. I have the original blades with brand new Trico inserts. I also have brand new Bosch Aerotwin wipers. Nothing works. The long 24" driver's side wiper acts like it's gonna jump off the glass. I've tried bending the arms, lubing the blades and a handful of other tricks and no change.
I'm at the point of wanting to redo the rubber mounts for the wiper motor assembly.
Any advice would be appreciated

 

Have you tried glass scratch remover ? Also I once used some oil and grease remover that had silicate in it, (I think it was drive-way cleaner), and that worked. I have the same problem with my MG TF, and it drives me nuts. Only problem is getting the time to give that screen a good go-over.

 

I've had a similar problem with both wipers. I'm trying Rain-X Treatment, and it seems to be helping by making the glass more non-stick.

 

I realized today that mine is both wipers also. I've read some saying rainx makes wipers chatter and others say what you're saying. I've been hesitating but I just might try it. I have a new bottle somewhere in the garage.

 

I'm gonna get some glass scratch remover ASAP.

 

Real fine steel wool works for this task, without scratching the glass like you might think it would.
