Windshield wiper starts randomly

[benz4life]

Title. Sometimes stops in the middle, or on the right side. Any ideas?

try spraying the wiper arm shaft with silicone lubricant... that does the trick on mine

The wiper arm assembly needs regular maintenance and lubrication to prevent sticky spots during operation.

If it starts randomly, then I'd suspect that it's a issue with your switch.

It's the stalk try pulling the cap off the stalk take out the spring in there and give it a good clean with electrical contact cleaner. Worked on a previous 202 we had. Or you could just change the stalk
