97' acura 2.2CL

I just replaced my power window in my driver side door...the pulley wheel it uses is made of plastic and it snapped.
But the thing is my window in my passenger door is really slow...and i was wondering if that would be because of a bad connection or a motor going bad?
Because i was going to try to fix the bad connection or use the old motor in my driver side door and try to swap them...because those things are $160 online new.

I was wondering how i can check for a bad connection?

and im also looking to buy a new clutch....im not really looking for a fancy clutch.. but the shop said that they wouldn't warranty or fix anything on the car if it broke because of the clutch if i bought it online. i was wondering if its worth the risk, its a lot cheaper...
I saw some excedy clutches? those any good? im not gonna race this thing
