Check ALL of the fuses and connections on the fuse pannel.
I have a 2003 GMC Envoy XL SLT. I was driving the other night and from out of nowhere my instrument panel lights started fading in and out. This did not affect the headlights, tail lights, or brake lights, warning lights, only thing affected was the brightness of the instrument panel lights. When they are not fading in and out, they are bright as normal. I notice however that when I turn on the headlights and fog lamps that's when the issue arises. I am thinking it is the instrument panel dimmer switch (see photo). Is there something else I should be looking for? Ive hear it could be the alternator but wouldn't that affect everything? I do realize that at night with the headlights on, that the instrument panel lights dim somewhat to make it easier on the eyes. but, the lights are going completely dark at times and then going back to normal brightness. Adjusting the instrument panel dimmer knob has no affect other than when I turn it all the way to turn on the interior lights, which works fine.
I had the same problem with my Jeep Wrangler. My tail lights were also not working. Turns out the same fuse controls both (at least in my vehicle) and when the tail lights go out, the dimmer goes out so you know there's a problem. Check your fuse.
This is usually an indication that the dimmer switch is in need of replacement.
you can not put a normal dimmer on a florescent light. You need to install a dimmer made for flourecent lights and they are expensive about 50 dollar around here. If you want to dim it put a normal incandescent bulb in the fixture.
You can use incandescent, fluorescent or halogen lighting fixtures meant for indoor use inside a home. For example, you can purchase incandescent wall lights that are connected to a dimmer switch with incandescent lamping. Fluorescent lights might be in models of ceiling lights, chandeliers and pendant lights. Fluorescent lights are energy efficient lighting choices. Halogen lamps are used in some recessed lighting for indoor use. Floor lamps may also use halogen bulbs. Read carefully to see what type of indoor lighting can withstand damp settings such as the bathroom.
the dimmer switch that controls your dash light brightness may be bad.
Check dimmer switch.
instrument panel lights for 1998 ford explorer the fues is good and when dimmer swtich is good
turn the dimmer switch up.
I would check the headlamp dimmer ; it is possibly fried.
If none of the lights dim (including dash lights, speedo, etc) the dimmer switch is probably bad.
Instrument lights fuse blown. ANSWER #2 There is a dimmer switch that controls the illumination of the instrument panel; it may be bad or may have been accidentally turned OFF or DOWN while cleaning the dashboard.
the dimmer rehostat is faulty..if you drive with the dash on full bright all the time anyway you can jump out the dimmer by jumping the two end wires on the dimmer plug
Answer 1 - Instrument Lights Operate IntermittentlyWithout doing a "hands on troubleshooting" of your vehicle, no one here can be certain of the specific location and cause of your problem. However, based on your question, I suspect that the cause is a loose connection in the circuit providing power to the instrument lights, or on the instrument panel circuit board itself.It is possible also, that the instrument panel dimmer switch is wearing out.Answer 2 -The dash dimmer switch or the headlight switch is the most likely problem.
The tripmeter knob located near the odometer on the instrument panal can be rotated left or right to accomplish this.
There is a fuse. There is also an instrument light dimmer. Make sure it is not turned all the way off before going any farther.There is a fuse. There is also an instrument light dimmer. Make sure it is not turned all the way off before going any farther.
On many cars, there is a dimmer switch which controls the instrument panel lights. If this switch is turned all the way, it may cause the overhead light to come on. The overhead light will then stay on even after doors have all been closed. Find the dimmer switch, close the doors, wait 30 seconds, and then turn the dimmer switch.
