Ok so after months of sporadically replacing and checking various things as they come to mind I still have no answer as to what is causing my dashlights, side markers, tail lights and plate light not to work. Here is a recap. One rainy gloomy day I went out to my car to find my lights not working after having been working an hour before. I have checked all fuses, replaced my headlight switch, and replaced my stereo wiring harness. Still nothing. Would a single burnt bulb cause all of this to not work? Is there a relay under the dash in between my fuse boxes and the lights? Could I have a ground messed up somewhere? Im not sure where my grounds are exactly so if that could be the case, any way some one could tell me where to check? Am I on the totally wrong track here? I have come across numerous posts about people having the same problem and no one has posted weither or not they have found a solution to their problem. Pretty please help. Driving after dark would be great!! Thank you in advance!

Using a 5th gen here, have you tested the "dash dimmer"?

NROD065

tested as in turned it to see if it was turned down? lol. yes i have done that. i havent taken my dash out so if there is something back there i should check no i have not.

Also.. another question. Im thinking that my battery is about to take a crap could that be the cause of it?

honda accord starting year 1998 and newer has a more complex electrical system. it uses serial data to communicate. therefore when you turn on your headlight switch it sends a command to the driverside multiplex control unit. the multiplex then sends the command to the passenger multiplex then both unit turns on your vehicle's lights.
if you have any good known multiplex laying around that should fix your problem.

Dimmer - Not in turning it up, as in testing it.

thanks for the replies everybody! tomorrow i will test the multiplex unit and the dimmer switch, and let you guys know what i find. we have a high of 27 degrees tomorrow this ought to be fun!!! thanks again!

one more thing... i dont have any multiplex units lying around the junk yards around where i live never have anything honda related and the drivers and passengers arent the same, any other way to test these? ( i dont really want to shell out 200-300 dollars for a new one unless i know that is really what is going on.)

sounds like an open ground I'm not sure where the grounds are. The lights are hooked up in parallel so one burned bulb wouldn't be the culprit. Find out where your commom ground is they should share. Also I would remove bulbs from sockets and make sure the connections are free of contamination. If you have a volt meter test the ground side of the bulb and if you have more than one volt then you have an open ground in the circuit.

Pass side under dash fuse panel - check the #1 10 amp and #2 15 amp fuses AGAIN. Are you getting 12v to the RED/GRN wire going to the combination switch?

NROD065

ok so i have zero volts coming out of the red green wire with the switch in all positions i replaced the switch with a brand new one a few weeks ago so im pretty sure that it isnt bad. i figured out the side lights work when you wiggle them a little where they splice into the front blinkers. but still no dash lights or tail lights.

poorman212

No voltage on the red/green into the switch? Are you sure you checked the pass side underdash fuses.....do you have the "auto lights off" feature on your Accord?

NROD065

the number 1 and number 2 fuses on the passenger side you said to check are wired to the sunroof and power seats and i have neither on my car. and no i dont have auto off lights. any more ideas? this is getting to be so confusing to me. im about over it lol

poorman212

Sorry, need to learn how to read my own wire diagrams. Fuse #10 (footnote #1, 10amp for sedan- footnote #2, 15 amp coupe)

NROD065

ok thank you i will go back and check that one again. still passengers side right? if anything i will just change so i can be super positive that it is good

Yes, pass/right fuse panel....sorry for getting it wrong the first time. Back to the question about getting power (12v) on the RED/GRN......no power ther then the fuse is?????

ok after not being able to log in for a few days i just created a new username. i think it has to do with facebook changing security i was just using the quick log in. but the fuse fixed it. apparently i just didnt check it properly. thank you so much im glad i can drive at night again. and feel like a major dumba** but i guess i got a good laugh at my own expense thanks again
