Cluster Brightness
 

Just noticed that my dimmer wheel only adjusts the brightness of my high cluster gauges, not the information display (but the MID will adjust from dim to bright) - i recall both would have some degree of adjustment in brightness. Positive.

Did I lose a bulb? Is the wheel pot contacts dirty?

When I flip off my headlights, the info display returns to normal daylight brightness. Lights on, only one mode - wicked dim.

Strange. Thanks!

Circled not getting bright when wheel is all the way up.

Pretty sure mine dims. I will check. We are talking about the part circled in red correct?

Yep, I know it used to, I remember the red bars on the side would be really, really bright when I had it cranked all the way up.

Now it stays at the lowest dimness, no adjustment. Gauges barely adjust. Thinking it's the rheostat. Just want to confirm from others who've may have had this issue... before I go pulling the cluster.

How does the headlight switch come out, just pop out?

Do you get any dash light flickering?

Nope. Just lost the ability to adjust the brightness all the way up.

To remove light switch, first remove air vent above it (gently pry it off).

You'll find two Phillips head screws under there - undo them, lift the switch up a tiny bit and pull it straight out.

The wiring is short, so you may have to pull the plugs to get at it properly.

The light switch is directly attached to the LCM, but it can be removed - can't remember exactly, but it basically pulls away (there may be some plastic clips to work out)

Are they aftermarket / upgraded headlights?

My dash illumination brightness control goes wrong every time I turn on my cheapo Chinese head unit. With the stereo on, everything goes to max brightness regardless of rheostat position. As soon as I turn the stereo off, normal operation is resumed.

Yeah, I just finished my projector retrofit. Great

Heres a thought - lets figure out where you tapped for those angel eyes on your trigger wires - If you tapped the wrong place, you could have problems with the dimming on your cluster

I tapped my trigger directly to the LCM in the factory parking light position, verified with a multimeter - no dimming or brightness issues -

Ah ha, let me pull the fuse on the relay and find out! I tapped a random 12v ACC on wire under the ECU cover.

^If you want the always on, you probably need to tap the red with white stripe I believe wire. I wired to the LCM so I could use as factory parking light operation - Per JB's thread (note that some also had a problem with dimmer brightness as they most likely tapped the wrong wire) - and see my last post in the thread for my notes on when I ran my trigger
