Rear wiper slow
Rear wiper on my RDX is very slow, today it even stopped mid-cycle pointing straight up on the rear glass. With the wipers off there is resistance when I push it - it’s not loose. If it’s stuck, I can get it re-started by manually nudging it to get it going, but it seems to cycle slowly. I’m guessing I need a new motor, but I have not found any videos online explaining replacement. Has anyone else done this replacement, or know anything about it? Is it just removing the trim on the rear door, then unbolting a motor and reattaching? Any other diagnostic steps suggested before I buy a new motor? Thanks.

Here is the Acura Manual on replacing the wiper motor. Hope this helps

I rebuilt a starter for a friend because it was slow to start and it was not a connection or a battery problem. I know it is a starter, but an electric motor is an electric motor.
Wiper motors are set in a worm drive mechanism (for torque). Check the brushes, clean it, grease it and you are likely good to go. I have rebuilt these on my beaters when I was young.
Before:
After (same part):
If you are handy, these can easily be cleaned and rebuilt.
