Greetings...... “Hi, I’m Don (aka MOLurch) and I look forward to helping you!”

Typically it is the Window Motor & / or the Regulator on these vehicles.
You need to test the Reversing Ground - & Voltage + at the Motor & at the same time have a look at the Regulator to be sure there is nothing broken or snagging.
IF Testing at the Window Motor proves bad, then follow these steps
.

Use of a VOM is needed to test
The way it works:
Ignition On
Switch held in Up position
One wire will have 12 Volts +
One wire will have Ground -

Switch held in Down position
The wire that had 12 Volts + is now Ground -
The wire that was Ground - is now 12 Volts +

If Voltage or Ground checks good at motor, replace motor.
If Voltage or Ground does not check good:
Check Switch Voltage & Ground.
Check for broken wires at Door / Kick Panel Boot
