Anyone know how to fix this?

I'm driving on the highway, in the rain, astonished on how well RainX windshield cleaner and water repellent works then my wipers stop in the middle of my windshield. I get to my office and turn the wipers on and they work but once I turn them off they go all the way back down and jump up and stop about 3 inches higher than they should be.

New Wiper Motor or adjustment? I searched DIY's and couldn't find anything on adjustment. Getting my Bentley Manual tomorrow.

Thanks

I have the same issue, sometimes it has to do with the relay, otherwise it is a new motor...I am pretty sure mine is the motor, but you can try to relay first, $20 try instead of just throwing $300 at just buying the motor if you DIY.

Anyone know the proper way on how to Remove and/or clean and check the Wiper motor Relay? I'm really hesitant on opening the ECU box and screwing something up. Do I need a special tool for removing the relay? Also, some of the below posts say to disconnect the battery before starting the car after you change the wiper motor or you may blow some fuse, i.e. #54 (I think). Dumb question, How do I disconnect the battery and will this have any unintended consequences? Sorry for the possible dumb questions, was hoping to have my Bentley Manual by now.
