Need diagrams for replacing driver’s window switch

The rear passenger window goes down, but not up from the driver’s door switch. It works fine from the passenger door. Toyota wants to replace the entire switch, but since it was working for about 8 months (we bought it used) and sudently stoped working. I am thinking that it just might be a loose cable conection or a dirty contact. I am looking for any Toyota diagrams or home-made videos for taking the switch from the door, in order to use some electronics spray cleaner and checking the connections. But I do not want to break any plastic clips or parts in the process. Thanks a lot in advance.

 

Thanks for the reply. I never spray directly, just on a microfiber cloth.

 

That’s it. Thank you!
