I'm getting desperate


I have a problem with the master power window switch and i'm getting desperate as i don't know where to start.

the switch sometimes works sometimes doesn't, not sure what triggers the action.

i have checked all the connection, switch, cables, door main connector, all looks good no rust.
dealer wants 200 bucks for the master switch and i can't return if it's not the switch.

some suggested that it might be the actuator, regulator or even power window mirror.

how many parts can be causing this issue and where do i start?
Thank you.
