LDC problems
Have a 96 coupe, Lt1/auto. The display is barely readable, but all the
information is there. Any ideas of how to enhance this information???

Your display is beginning (or has) to give out.
Get in touch with Brian at batee.com. He has done work for lots of us (he did my climate control on my 89) and he is fair.

Does the displays light up with the key or light up turning on the parking lights?
Take a flashlight and shine it at the photo cell (it's above the fuel info button on the dash with all the other buttons). Then put your finger over it. Is there a change in brightness of the dash display from bright to dark.
Need to do some research to get additional information and a direction.

I believe the 80s cars use the polarized film that goes bad. The 96 (and 90s) care are not like that, they use LED displays.
There are many items that can be the problem. The photo cell sensor, transistor driver, and CCM.

The photo sensor seems to work. Bright with flash light, dark
when covering the photo sensor.
Problem is the bars or numbers are very weak???????

So we are talking about the rectangular speedometer display only ?
Is the tach, lights for the 4 gauges and red indicator lights OK ?
Double check fuses # 27 & # 38.

When the light sensor in the dash is at its lowest resistance it drives the display to full bright. Not easy to get to the light sensor does go bad and I don’t have much info about it. I assume the dimmer control on the headlight switch works OK (?).
Depending on where you end up and running out of ideas, possible the instrument cluster could be re-seated and give it a visual look.
