SO looking into it a bit more.. my backlight only works with the parking lights on. I know the Photo sensors work.. so it is either a bad wire to the CCM, or the CCM is bad for that circuit, I am hoping it is just a wire.

My '92 it's on bright in garage or outside. Only time it goes dim is w/ headlights on when it's dark outside.

Fixed.. easy one luckily.. just needed to reseat the connector on the info center

revisiting this...

LCD Dim in the the garage and while driving. Photosensor works, if in the daytime I shine a light into sensor LCD gets bright, remove light it gets dim,

I need another favor for those with 1991-newer. My guess is checking this in the garage will be most noticeable..

key on- Not running, are the gauges backlit as well?
If you adjust the brightness on the interior lights (light switch is off) does the dash get dimmer or brighter as the light dimmer is adjusted?

Thanks

92, in the garage, key on not running. Gauges are backlit. No change in brightness if the light dimmer is adjusted.
