I am having an issue with my passenger side power window not going all way up. It will go a little past half way up and hang with the motor gear clicking. This issue continues after I replaced the motor with a new one. The plastic gear on the oem motor was stripped and I will strip the new motor plastic wheel if I continue with my attempt at repair. Where should I start with this?
I suggest removing the regulator as that's key to checking the mechanism and removing other parts that may have failed. I'm guessing that one of the rollers has broken so something is no longer in the proper track.
Get a can of spray grease with long a tube and spray all the tracks, rollers, gears, pivot points, etc.
I was amazed how much this helped. The old grease gets hard and sticky.
When you did the work, did you replace the assist coil spring? (was the old one still there?) That spring takes a lot of weight off the motor to help the window go up. Other than that, most common issues are old caked lube, worn runners, electrical connection weak (frayed wire in the door?), etc.

Be careful with spray lubricants inside the door. Some of the most experienced people here say that doing so is very likely to cause problems with the door paint as much of it will land on the back side of the door skin.
The only proper way to deal with old, sticky, grimy grease is removal, thorough cleaning and replacement!
The power window mechanism in C3s is very sturdy--the frameless design DEMANDED this. Once problems are noticed after decades it's time to completely disassemble, clean, relubricate and replace as necessary. The motors were also very strong and durable. Broken/stripped teeth is a near certain sign of a problem that has nothing to do with the motor!
Spray lubricants are useless with window mechanisms. There are some significantly loaded parts with sliding members. Spray lubes have very little actual lube content. The factory used white lithium grease when these things were new. They need at least that much lube, at this stage of their life. Grease from a tube or can is what you use.

There ARE spray greases that solidify, vs just spray lubes like wd40 that only contain a small percentage of oil. They are thin enough to spray into hard to reach areas and then rapidly solidify to stay put. Also, the evaportive solvent helps to soften and flush out some of the old, hard, sticky grease. I think the stuff I used ended up just as thick as the can of white lithium grease I have.
As I said, on my windows, the results were amazing.
If you're worried about getting some on your door skin, you could stuff some rags behind whatever you want to spray.
