if you have a meter,, disconnect the wires going to the switch , put one lead on each side of the switch and move the switch ,, have the meter set in Ohm mode, if it moves , the switch is ok, if it stays at 0 ,, its done ( hint, tap the back of it lightly if its dead,, it may have fused together and sometimes this will break it loose)
Use a test light to see if the motor is getting power. If it is then motor is bad. If it is not getting power "jump" the wires on the switch to see if window will operate, is so switch is bad
Check to see if you are getting power to the motor if so window motor is defective Could be open wire usually in the door jamb area
To test the power window switch on a 2000 Silverado, first, ensure the vehicle is in the "On" position but not running. Use a multimeter to check for voltage at the switch by connecting the probes to the switch terminals while pressing the button; you should see voltage when the switch is activated. If there’s no voltage, the switch may be faulty or there could be an issue with the wiring. Additionally, you can test the window motor directly by applying power to it to check if it operates independently of the switch.
First test to see if the problem is the switch, wiring, or the motor. Here's howhttp://www.ricksfreeautorepairadvice.com/repair-topics/window-power-repair/test-power-window-motor-and-regulatorThen replace the regulator if the switch and wiring test good.

Remove door panel to check wiring to switch and motor See if motor is getting power through the switch - if so motor is bad If no power to motor check operation of switch - jump wires to test if window works bad switch
If only the window on a 2000 Montero Sport is not working, the issue could be related to a faulty window switch, a blown fuse, or a malfunctioning window motor. First, check the fuse related to the windows to see if it needs replacement. If the fuse is fine, test the window switch and wiring for any defects. If those components are functioning, the window motor may need to be replaced.
Disconnect wires from motor and check to see if you have power and ground going to motor--if so motor is bad if not have to check wiring and switch to that motor
Bypass the switch with a jumper & see if you can bump it with a hot wire.
i would first check to see if power window master switch is good usually if more than one window doesnt work, that's where the problem isfords also have a lock on the master switch for windows other than driver window. check that is not engaged
It's most likely either the switch or the motor that is bad. The switch is cheaper... See if a service center at a dealership can hook up an OBD computer to your car to test the switch. If not, you have to start replacing parts and see which is bad. See if a salvage yard near you has these parts - it will save you a lot of cash.
I would suspect the switch first. The next time it fails remove the door panel, unplugg the electrical connection at the window motor and probe the plug with a test lamp to see if the motor is receiving power when you work the switch.
First, check to see if you hear anything when you try the window switch, if nothing and the other window works probably the window switch. Could also be the motor but try the switch first, it's a lot cheaper.
