Power window weirdness

[9t3lightning]

Ok group
My 90 wagon's drivers door window motor is a problem .
Now this is my daily driver, and replaced the window motor twice , once with a JY part and the next time
A new motor. Now today go to use the window and nothing. All other Windows work
Is there a way to test the switch,?
Can't see another motor being bad again?

mOST OF THE AFTERMARKET motors can crap out way before a ford one. Have had used ford ones last longer than new ones

First check for voltage at the motor plug.

As mentioned, check for voltage first. If voltage is good, try another junkyard motor, however, this time pull one from a passenger side rear door. This is the same part as is used on the driver front door and will have seen much less use than a driver door motor.

This is what I essentially did on my '90 GM. The original driver door motor would randomly decide it didn't want to work. I swapped in the rear passenger motor and pulled another rear passenger motor from the junkyard a couple weeks ago. Both motors work excellent. My driver side front window rolls up much faster than the passenger side. At some point I'm going to pull a driver side rear motor to use in my passenger front door.
