Last night I went out in the truck and knocked the wiper arm to get an intermitent wipe and the blade went half way over and got stuck then tried to move again and got a couple of inches then stopped again.

If i put in on 2nd speed or fast no problem but intermittent or knock the lever it gets stuck,

Any suggestions greatly appreciated.


Thanks james

quite possibly the switch is buggered at that setting.

Arr thanks for that, only thing i could think of was the nuts need tightening up nd the motor is slipping between the arm,
