4 Lo light stays on... Power window motor

[GT11]

I put it in lo 4 and the light on the console comes on. When I disengage the lever back to 2 wheel drive, the light on the console is still lite. Indicating the truck is in 4 lo. The lite will go out in time. Could be a sticking switch? Where is it located?

Thanks

PS....Even though the drivers side window barely works. I have decided to replace it and be done with the "Go 4 inches and stops" crap. Where's the best place to buy another motor?
