wiper chatter

[turboaddict2]

I have been driving my car in the rain for a while and the wipers chatter and its really annoying. I have the new Bosch excel blades too and they are fairly new because they don't get much use. ANy solutions to an annoying problem?

ckeck the arms and make sure they aren't bent (unlikely). Clean the windshield and try different blades. Typically, chatter is always caused by the blades.
