I have a 2000 civic si. When i turn on my headlight NONE of my instrument lights come on. Not the cluster, heater or radio. The CEL/seatbelt light/ gas light etc still light up fine but the illuminators dont turn on. IVE CHECKED ALL MY FUSES AT LEAST 10 times. Ive even swapped out the relays an still nothing. Everything else works just fine, even the radio dims down ALOT soon as i turn headlights on. My battery an alternator are 100% fine.

I really have no idea what to do here so any help will be appreciated cause this just has me stumped. I bought the car about 3 years ago an everything worked fine. I RARELY drove it an it was usually the car other people borrowed from me.

 

did you take it out and check the wires and plugs?

 

take out the cluster or climate control?? yeah all the wires are good everywhere. Its not like just the cluster doesnt light up. NOTHING lights up. When im driving at night with the headlights on its pitch dark inside the car.

 

The fuses may be OK but not making good contact ...

 

no the connections an contacts are all good everywhere that i can see

 

then buy a new one. they go bad

 

buy a new what?

 

cluster..or car

 

its not just the cluster that the illuminator doesnt work. everything else like climate control an radio dont illuminate either when the headlights are turned on

 

mine is doing the same thing. i haven't checked the fuses yet, but i'm hoping that's it =/ if you find a solution let me know

 

It's probably the dimmer switch. Try switching it out with a working one, or just try taking it out and cleaning it.

 

yup it was the dimmer switch thanks for the help
