1995 Honda dashboard will not illuminated, all other lighs works. I also check the dimmer knob to make sure it was turn up. Is it hard to replace the light bulb in the dash. Does anyone have a diagram showing how to replace the bulb?

The dash board has many light bulbs and the gear shift and the window switch all work on this circuirt. The radio if its stock turns up and down on this circuit too. The running lights are relaed to this circuit too as the runnings lights go out the dash does too. ( It's a DOT thang ) Lets you know that your running without tailights! But the dash can go out by it's self and aftermarket radios and their installers are the culprit. The dash light wire is in the stock radio harness and their used as ground wires and left to touch ground and blow the fuse. The fuse is called gaugesand it's a 5 amp or 7.5 amp. It's in the dash board fuse box behind the change holder that your left knee might hit if it were to hit the dash. If all the lights in the heater control and the gauges and the gearshift and the power window switch are all not working look for a blown fuse and it's cause. ( radio wireing ) or the running lights are out too and a bad marker light frunt or rear running lights. the park fuse may be blown and cause this and the dash lights won't work either. The dash dimmer switch can and does fail. It pops out by prying it out the frount theres 3 wires on it one is ground. one comes on with the lights and the other is the one going to all those light bulbs I just talked about. With the lights on one wire will be hot ( use a test light to check) A cheap one at the parts store or wally world only costs a few dollars at the most. If two wires are hot its on and it's godd one of these two will brighten and dim as you turn the switch. if only one wire is hot and the others stay cold the one that is hot jumpered to the one thats not black (ground) will make the lights work. Your right you could have bad bulbs but theres at least 15 of them and whats the liklyhood of blowing all of them at once ( doesn't happen unless theres a real bad problem involving crashes and jump starting. The cluster comes out by removeing the covers and then the speedometer cluster itself. If any of the lights work that the dimmer controls work and the gauges are't lit then this is the direction your going.

Try changing out the ignition switch if the dimmer switch doesnt fix it.
