Passenger's Unit
WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
- Before testing the power window control functions, troubleshoot the multiplex control system (see TROUBLESHOOTING ).
- Remove the passenger's multiplex control unit from the passenger's under-dash fuse/relay box, and disconnect its connector.
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.

- With the passenger's multiplex control unit still disconnected, make these input tests at the passenger's under-dash fuse/relay box socket.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 1 in DRIVER'S UNIT
