why rear wiper stops midway in cycle

thanks but done that - wiper still stops

You stated the motor is still turning .. Have you looked to see if the *shaft* is still turning when wiper arm stops? .. No reply now, ok well > Good luck to ya!

hi - shaft stops too

Replace motor assembly!

motor works - took apart the wiper arm mechanism - not too tough - first took off wiper arm. Next removed rubber guard, then large nut. Next trick was to remove locking washer - ended up drilling a hole in it til I could wiggle it off (could have just drilled it off and got another). Once off shaft came out from the inside. It was all corroded - sandpaper cleaned it and greased it up. Put it all back together - wiper works as good as new.

yay

Yes! This was a $4 solution!! Thank you!
