Coming home from work yesterday (in the heavy rain) my driver's side wiper started swinging wide to the left. The wiper at times would swing past the glass and get stuck on the base of the antenna. Anyone know what happened and how I can fix it?

Thanks

 

Most likely the nut on the base of the wiper worked loose and the wiper motor ouput got twisted in the arm. Pull the trim cap off, then loosen the nut all the way and take the arm off. Then run the wipers through a cycle so you find the bottom stop, then put the arm back on and tighten it down. Then flip the wipers again to check the stop point. Might take a little bit of fine-tuning, but it's pretty easy.
