Pass' Front window

[69Charger]

Hi. The front pass' window is stuck up. Have tried the tapping it ideas etc but no luck.
I even got hold of another motor and conected it to see if it was the switch or the motor that was at fault. The motor by its self spun when i moved the switch to make the window go up but when i moved the switch to make the window go down nothing. I reconected the wire to the motor in the car and lisitened to the motor for any sound of it trying to work. When i moved the switch up a click sound came from the motor as if it was trying to make the window go up, but when i moved the switch to make the window go down again nothing. Any ideas please.
Regards. Shaun.

could be the switch itself at fault

Switch, or break in the wires in the door gap
