Every once in a while I will pull up to a stop, turn on my right turn signal and the wipers make one pass over the windows and stop. At first I thought that I had bumped the right stalk with the wiper switch on it, but I know now that I hadn't. It is happening more frequently now.

 

Chrysler products always seem to have little electric quirks.

My first car, a '72 Plymouth Duster, with the ignition off, if you turned on the flashers and pulled down the turn signal lever for a left turn and then turned on the radio, it would go tha-thump, tha- thump just like a heart beat. If you turned on the wipers they would move back and forth 2-3 inches at a time in time with the heart beat.

Report it to your dealer next time its in for service. I doubt he will fix it. But it may help if the situation gets worse and you need a warranty repair

 

ive got a ford F350 van that does that i think its the turn signal switch and wiper combo problemo
