Passenger Wiper Arm, lack of tension? TSB?

[Lil Abner]

I have an '09 2-dr LB. I notice that the passenger wiper arm likes to move up and down off the glass while driving. At highway speeds (65-75), the arm doesn't put enough pressure on the glass to get the really nasty stuff. I recently replaced the wipers with Bosch ION wipers. They are the slim ones with a slight airfoil on the top to help hold them down. And before anyone asks, no, they don't make a 14" for the passenger side. I bought a 16", disassembled it, and re-made it to a 14" blade.

Anyways, does anyone know if there is a TSB out for this? If not, I already have a second spring I'm planning to add inside the stock one for more force. But I'd rather an OEM fix. I searched, and couldn't find anything...

Thanks in advance.
