Dash lights

The dash lights ( on my 2005 Monaco Dynasty) to the Speedometer, tach, and other guages do not light while all the others are working......checked fuses and they appear all ok....any ideas as to what could be causing the problem?
Thanks for any help.

I would put an ohm meter on the fuse(s) just to be sure or replace. I've had fuses blow but it did not look like it from visual inspection.

Are the tail lights working on the coach? I know that on some cars if the tail lights blow a fuse or don't come niether do the dash lights. Not the brake lights , just the lights that come on with the light switch.

Check your light switch. It may be bad.

I had to replace nearly all the bulbs in the dash of my pickup last year. Only a few were working. Basically all your bulbs are going to be on a single circuit. If some are working it isn't a fuse issue.

If you do replace a bulb, replace them all.

If you have a freightliner chassis I think the dash gauges get there power from the gauge (I might have the wording wrong) module. The module is part of the enunciator panel with all of the warning lights. The power goes thru the light switch, then thru the dash lamp dimmer (may be part of light switch or separate like mine) then thru the guage module then finally to the guages. If some guages light then there is nothing wrong with the light switch, dimmer or fuses. With three guages out I dought that the bulbs are burnt. You may have a wiring problem or guage module problem. Do not use a test light (to much current) use a digital volt meter and check for power to each guage. Again, if you have a FL chassis, you can remove the guages from the front. Just twist the guages bezel a quarter turn to remove. Under the bezel you will find two small cap screws to remove guage.

If the gauge lights aren't working while the headlights are on, the headlight switch is bad. If you already checked the fuses. The rheostat on the light switch breaks. I just changed mine.
Merry Christmas.
