You almost cetainly have a bad earth on the light or more likely on a break light so the bulb ( in the brake light ) not the dash light , is having to source its earthing through the dash light and this makes more current flow through that light causing it to brighten. I am puzzled though as to what this has to do with a GPS , as this is where you have "posted" your query ?

Everything IS WORKING EXCEPT THE BACK UP CAMERA AND RADIO. The Camera stopped working shortly before the radio quit working. Are the 2 problems related?

Could be, but not likely. The back up camera gets power when the car goes into reverse. As soon as video is present, the screen switches so you see the camera. The radio has fuses for the light that connects to the instrument cluster light dimmer. Another gets connected to the ignition switch run wire so the radio goes on and off with the ignition switch. The last fuse goes to a wire that has voltage on it all the time. This is what keeps the radio station memory alive when the radio is off with the key. Locate those fuses in the harness on the radio to see if one is blown.

Dash lighting on my 2004 chevy avalanche

This is a known issue with this dash. You can replace the instrument cluster, have it repaired or diagnosed. It could be the dimmer control, the bus connections, the fuse block too.

2005 Chevy Impala, check engine light came do I reset it? Thanks!

Secret solution. Go to your advanced auto parts or napa. Some places won't allow this but give it a shot before you pay. Ask for the check engine light code reader go out plug it in under your dash and you can read or reset it. If you have a problem it will come back though.

Connect the hand break wire (light green) to the ground wire (black). It tells the system the hand break is up and even movies work :) .

I have a Lowrance LMS 320 GPS/Sonar and the screen does not light up. Power to the unit is there. Have tried soft and hard reset. Unit is 4-5 yrs old.

Are saying you can't read the screen at night, or is it hard to read the screen anytime?

If you tap the power key, you should here a beep and the screen should get brighter. If you hear the beep and there is no light, then the internal light has failed.

If you can't read the screen in normal light conditions try viewing it under a bright light at various angles. You may notice that the screen is just barely visible. If this is the case you may be able to fix the problem by adjusting the contrast. Try tapping bthe power key and then tap the right or left side of the track pad. It may take several taps to see the results. If left or right doesn't work, try up or down.

Did you try using the illumination and or dimmer wire? It has been different depending on application. So try ONE AT A TIME and that should fix it

Screen Brightness, battery is brighter then when plugged in.

mine the other way round, brightens when plugs into power source, but only marginally, enough to notice it though.
think is probably a characteristic of the electronics
