Dash lights

Are you sure you don't have the dim control set way down? If it is full on, check the fuses. Anything else that doesn't work? (i.e. interior lights???) They are on the same circuit.

Dash lights and radio lights dim at night

Strange behavior. I don't see a relay, but the components have logic circuitry. Not sure why--bad design. What I would do is test the dimmer. Unplug the connector and put an ohmmeter across the yellow and gray wires (terminals S and J). Ohms should go from infinity to zero as you rotate the dimmer knob.

I am having issues with my 1997 Chevy Monte Carlos. The engine will not start, however the radio, head lamps, and dash board lights all come on. In your expert opinion what do you think the problem...

if you just hear a clicking when trying to start the car charge the battery to full, all of the items you listed will work with a low battery , but it doesn't have high enough amps to turn over the car .

-my car is 2003chevy monte carlo the daytime running lights no longer light and at night the dash lights no longer light and the radio lights are dim as is the gear shift selector light. can you help Dave

Hi David, Look for grounds, especially the headlight switch it self... Most of the time the issue you describe is resolved by replacing the headlight switch. There is a variable resistor that fails, over time.

If the headlight switch itself is loose, proper grounding would fail, and current runs other places.

Both the radio and the gear shifter are affected by the dimmer and on or off status of the headlight switch.
