I have a 03 accord coupe 6spd and I've replaced both regulators in the doors and my drive side goes up and down but my passenger side doesn't but when I push the buttons on either door it just makes a clicking noise

 

1. Check under-dash Fuse No. 26 (20A). If fuse is good, go to next step.
2. This is a test you can do to see if it is the driver's door multiplex control unit. At the 23-P connector for the door multiplex control unit, attach a wire to cavity # 3 (where the WHT/GRN wire is), with the connector plugged back in, turn the ignition to ON. Ground the WHT/GRN wire to body and try to operate the passenger window. If it works with ground to the WHT/GRN wire; but, doesn't when it is not grounded, then it is a faulty door multiplex control unit.

WHT/GRN is a white colored wire with a green stripe running through it.

 

That diagram shows for a four door and mine is a coupe and it's the passenger side that don't go up or down that's my problem

 

The driver's door connector terminal pin for coupe and sedan are the same. The door multiplex control unit (mcu) is in the driver's side, which is part of the power window circuit for both sides.

The diagram is for multiple years, and for coupe and sedan. The asterisks denotes differences.
