A "clicking sound" is not how you diagnose the issue. Grab your digital multimeter, unplug the motor, hold the switch and check for voltage.
If you have voltage it's the motor, if not disassemble the switch from the seat, grab the wiring schematic from the FSM or a Haynes/Chilton and check continuity through the switch.
No clicking MIGHT be the switch, or the snap/spring/something just broke off the little tab that makes the clicking sound. Snap switches can be stupid like that but still work.
