Window?

When pushing the switch do you hear any movement inside the door?
Try up and down
If you do that’s mean you may need the regulator
If nothing it may be switch or wiring or motor
How to take the door panel off you have to look around the edges for screws and in the middle
Take them out remember the inside door handle too
Once panel out reconnect the window switch
You need an electric volt meter or you can use a test light
Work the switch while testing the wires at the motor for B+ and B-
And work it that way

Good luck
