PWR window amp problem

[drftkng951]

lately my window has been giving me trouble. depending on how hard i shut the door means my window wont roll down.
seems like the connection between the harness and amp are loose. so in order for my power to work i have to push the harness into the amp a certain way for it to work.

my question is, how can i fix this loose connection so i don't have to take my door panel off to roll my window down/up

what year is your car? it might be a loose solder joint in the amp

My car is a 91 SE
I saw DIY thread on soldering, could it be just that the contacts are dirty?
And by me pushing ont starts a closer connection between the harness and amp.
Is there a way to clean the contacts safely?
