Snowing/raining here last night and I absent mindedly left the intermittant wiper switch on when I shut the car down. I realized what I had done when I went to start it up this morning. The wipers jumped a bit but were of course frozen to the windshield and did not move any further. I quickly shut of the switch and proceeded to clean off the car. Once back inside, I turned on the wipers and only the driver's side worked. I fiddled with it a bit but had to get off to work. Any ideas? Connecting shaft broken? Maybe an adjustment clamp slipped?
