the other day we had a bad snow storm in chicago, well anyways, my driver side wiper began to make a weird noise. Sounds like it may be coming from the motor. i took of the wiper arm off and turned the wiper switch back on, the noise still continued, did anyone have this problem before?

 

fixed it, took the arm off sprayed some wd-40 and cleaned with a wire brush, must of had some salt in there or something
