hi honda tech

car: civic 1994 si
problem: light interior doesn't work
light in question: cruise control (switch) , climate controle ( X2 bulb light, speed&temperature), sun roof (switch) and the roof light when i open the doors.

tanks for you help

 

Have you checked fuses?

 

The cruise switch works, just doesn't light up? Replace neo wedge bulb
Replace bulbs in climate control
Check dome light bulb, if not burned out, check voltage and both door open switches.
Check sunroof fuse, relay and switch for proper operation

 

The cruise switch works, just doesn't light up ? yes, all the the fuse is ok. thanks for your help

 

Im sure the bulbs are bad in the cruise control, climate control, speed/temp and sun roof, thats pretty common. As for the dome light, does it turn on when you put the switch to on?

 

if your bulbs are fine, i suggest you Ohm that fuse because some of them are undercover bad ones in disguise. just to make sure.

And if your fuse is fine, and you replaced/checked all your bulbs. . . turn your dimmer up lol.

 

yes and dimmer switch work.

 

did you check BOTH fuse boxes for the interior under the steering column ?

 

yes

I will change the switch to see.

 

Sounds like a bunch of blown bulbs and a bad door switch.

When many bulbs are blown, it's sometimes a sign that the alternator may be overcharging the system. You may want to have the alternator tested.

 

i don't think it's my alternator

 

Aftermarket radio installed? If so and the "illuminate" wire I do believe was hooked up, causes the Dimmer switch to short out, and if that happens, the lights in the clutster short out and you have to replace the cluster, as well as the dimmer switch.

But remember to UNHOOK that illuminate wire, or w.e it may be called.

 

Is this a guess or did you test it?

 

yes i guess.

When I bought the car, I found it. I have all changed since.
