My passenger seat motor just clicks with no seat movement help please!

 

because of the age of the car broken wires are not uncommon, particularly if switch is on door. The click is probably the transmission solenoids. The motor should be attached to transmission under seat it will have a 2 wire connector with a test light see in lamp will light when connected across connector. The relay is also mounted to seat frame 2 connectors one for motor the other for switch. Unfortunately I do not have wiring diagram to give you colors. The Power seat motor draws alot of current and tended to overheat connectors. You need to probe connectors to see what is getting voltage. It's a start.....
