Hello, I have a 2003 Honda Accord V6 EX with Automatic Transmission. My passenger's side window will not wind down. I recently replaced the driver's side switch and the driver side works now. I ordered the one for the passenger's side. I am more concerned about the remote to lock and unlock the doors. It does not work. I replaced the battery to ensure the battery is good. It does not open or close any locks, does not pop open the trunk, and i have not tested the panic button on it (prefer not too). Anyways I was reading and a lot of people are saying it could be this multiplexer control unit. The thing is, I tried looking it up and I find out it is inside some Fuse Box. Now If I order the fuse box does it come inside it? Or do I have to order them both? Also can someone show me the correct part number I need for my vehicle? Also the door lock button does not work on both doors. Thanks

 

Maybe your key just needs to be reprogramed, or you need a new key, if none of the buttons work. Do you have a second key? You can check the panic button, just push it again if it goes off, and it will stop. Yes, the multiplex integrated control unit is part of the under-dash fuse box. It will cost you quite a bit to replace, so I would make sure that is the problem first. If the multiplex was bad I think you would have more problems than just door locks.

 

1. Like EXV6NIGHTHAWK stated, reprogram the remotes since you recently replaced the driver's switch. You must reprogram all the transmitters once you're in programming mode. See page 9 of this TSB for programming instructions for your car:

Honda TSB 98-011

2. For the passenger side window (front), check the No. 26 (20A) fuse in the under-dash fuse box.

3. Just curious, is this a sedan (4-door) or coupe (2-door)?
