Anyone know what can cause the information (mileage, temp, ect) to bright up and dull again real quick. Its like a flicker but it doesn't go out, it gets brighter for a second then goes back. It mainly happens when im not moving. Driving to work today, and seen it happen 2-3 times, but when I was at stop lights, it kept doing it non-stop.

perhaps the is a voltage regulation issue. how are the headlights?

Short somewhere.

Rydis

lights are fine. The only thing that seems to be wrong is the information center.

Mine actually does it too when i'm coming up to a stop.. Headlights dim as well and then brighten back up, and mines an 08.

creedin

is it when you first start the car in daylight? what happens when you start the car is the lights are dim, then it will brighten to normal then if its not dark enough it will dim again, but only once

Rydis

nah, it was at like 6:30 this morning. Still very dark, but its did it more then once.

aftermarket CD player?

I have the alpine 9884. Tested it again last night. Nothing else fades, not the headlights, not my dome light, the the illumination on the stereo, just the DIC.

are u sure u didnt plug something to the GM lan wire. when it does it turn off ur radio and see if it stops

I have noticed in the past that the electric power steering causes a huge drain in the car's electrical circuit.

my car has done this since driving off the lot. pretty sure it happens on a regular basis.

Rydis

yep im sure. I also now notice it only happens when the headlights are turned on.

well from warrens post it sounds like an issue with the car itself. since its intermittent it sounds like a bcm issue so you can try getting it "fixed" at the dealership but they probably will blame aftermarket and probably be no help

Rydis

Might have to take it in anyway. As it gets worse, it now whines (like a bad ground)...but only when headlights are turned on. Still can't figure out, since headlights still function fine.

huh odd

Rydis

Actually, just found it its not just the odemeter. Also parts of the intrument Panel. The highbeam light will do it also, but not the red seat belt one. the CEL wont do it, but the bettery light will.
