Dash lights not working
New member here.
Let me jump in on this thread. I just bought a 2000 Accord LX V6. The previous owner installed an aftermarket radio. Since then, the dash lights don't work. He put in some of those strip lights with the sticky backing and plugged them into the cig lighter for power. (I don't know how he could drive like that, they're so bright you could perform brain surgery under them)
Several forums address this question. Most suggest that the radio installation may be to blame, and others cite a multiplex unit. Our closest local Honda Dealer, Lia Group, (don't get warm fuzzies talking to them) claims that the forums are wrong and that radio or multiplex have nothing to do with it. They want me to bring it in for diagnosis. I'm seeing $$$ here.
On the bright side, I have the original radio, and another local dealer, Mohawk Honda, (they're much better to do business with but farther away) says they'll take out the aftermarket radio (which is a colossal pain to operate anyway) install the original for $93.
Anyone have any thoughts that might help?
Thank you all so much

when you installed the aftermarket unit, you connected the orange or orange/white wire incorrectly and shorted out the dash lights.
disconnect that wire, replace the fuse, and you'll be back in business.

2000 Accord - dashboard help
Hi, looking for some help in a similar vein - 2000 Accord EX V6 dashboard gauge lighting has gone out. Warning lights and the P-R-N-D lights still work fine, but all gauges are completely dark when the headlights are on.
I tried fiddling with the dimmer switch and it still seems to be functioning, as I can still dim and brighten the gear selection lights. I haven't installed any new electronics in the car anytime recently. I have also read about multiplexer controllers failing in these cars - would warning lamps / P-R-N-D still work if that had failed? I used to be able to make the lights flicker back on by beating around on the top of the dash, but no more - this is making me think there may be a loose ground or some main switch with a loose wire. Anywhere I can start looking under the dash for something like this?
Thanks in advance for any help.

Hi redbull, double checked no. 9 fuse and it's fine. I'm thinking it's got to be some kind of loose wire given it's intermittent failures to start with. Is there a central gauge lighting switch or anything behind the gauge cluster?

If fuse is good, then check Ground connection G401. If no change, then if you have a multimeter, test the resistance (ohms) of the dimmer switch.

OK, checked out the dimmer switch which shows 0-20,000 ohms on the multimeter. I also looked at all of the pins/connectors/wires for any signs of damage or corrosion and everything behind the gauges looked perfect. Each of the bulbs looked good, and there were no signs anywhere on the circuit card or wires of any kind of short/burning/etc. Any other ideas? If the multiplexer had failed, would I still have PRND and idiot lights on the dash? Is there another master lighting switch somewhere that could have failed? Thanks again in advance.

So, the ground connection (G401) was checked?
Yes, it may be a faulty driver's side Multiplex Control Unit. Certain indicator lamps may still light up even if the lighting for the gauges do not work.
There is no other master lighting switch.
This link is the recall for certain Accord V6. However, even if your car was not on the VIN list, it may be a faulty Multiplex Control Unit.
