My rear wiper jet wasn't working so ordered a replacement.

Got it fitted no problem and went to test it - it wouldn't stop and the wiper arm wouldn't stop either, I had to turn the ignition off.

Turned back on and to test again and it kept squirting and wiping before the wiper blade stopped mid wipe.

Haven't yet investigated the fuses yet but does anyone have any experience in this?

My symptoms from when I picked Fatty up
Rear wiper would sweep on ignition on and stop randomly (No park) No intermittent, would sweep 3 or 4 times and stop wherever. No rear squirt.
Fault traced to the Bosch box of tricks on the rear wiper motor. Couldn't find that individually so ended up getting a replacement rear wiper assembly courtesy of Stacker. All hunky dory since
