Rear wiper motor removal DIY somewhere ?

[edco]

Greetings all
Well I will only admit this to my dear XOutpost friends.

I actually backed the car into the garage with the top hatch OPEN !!

Yes, I know. Dunce cap for ed.

OK. Now what actually hit the top of the garage was the bottom of the rear wiper. It still runs but doesn't come to rest flat and seems very "wobbly" in place.

Having searched on here and found several images, I am going to guess that the threaded rod that goes from the motor to the arm is bent slightly.

Therefore I suspect I will likely have to replace the motor and I cannot figure out where the trim catches are to get to the 3 bolts that seem to hold it in place.

Please be gentle with me. I already have an embarrassing dent in the aluminum garage trim I have to try to minimize - right, like I work at "Dent Wizard"...not.

Thank you in advance !
