Well lets start with the basics. Did you check to make sure there wasn’t a burnt relay or fuse in either one of the fuse boxes on the inside or in the engine bay. If all the fuses are good then either there is a short in the wiring system, the motor you bought was bad, or the switches that control the windows have burnt out. To check for a short you will need a wiring diagram and then you’ll need to trace every single wire and check for damages.

Was the motor you installed brand new or used?

I agree it sounds like an electronic issue not a window motor since u have already installed it and Im assuming its new. It would be a fuse/relay, circuit break, ground fault or possible bad switch. Best way to test this is to take a multimeter to it and see what u get for voltage or continuity.
