This will depend on what is wrong..........
You will need to remove the Door Panel
click Attachment below
Check the Regulator for binding
Test the Window Motor for "Reversal Voltage & Ground"

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
