sorry for the delay............
Greetings...... “Hi, I’m Don (aka MOLurch) and I look forward to helping you!”
IF you replaced the Window Motor with New or a know "working one", then this can be the Regulator (I like replacing "both" the Regulator & Motor as a unit), Wiring, or Switch.
The way the Window Motor works is there has to be "Reversal Voltage + & Ground- at the "2" wires of the Window Motor.
Here is testing procedures:
Use of a VOM is needed to test
The way it works:
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
