Help with 2000 Bonneville Cluster
Hello everyone, I currently own a 2000 Bonneville SE 3800 Series II. It is a great car, but I am having trouble with the interment panel illumination. At first I thought that there was a loose connection, but after fiddling around for a few hours, I took it apart. I see that there are 8 bulbs that create the illumination effect. I hooked one of the bulbs up to a 12volt power supply, and 4 of the 8 lit up (The one that i touched did not.) Which is fine, it is understandable that there are 4 bulbs are out after 10 years of life. Now the only problem is, why are the four not coming on when i plug the entire cluster in including the red bulb for the systems monitor? So at night, the only bulbs are are illuminated are the PRND321 lights, both blinkers, the MPH back light, and everything else that is LED. I am just wondering why no illumination light bulbs are working, but all of the LEDs are working. I am trying to diagnose, but trying to do such a thing with the ribbon cables is extremely difficult. If anyone has some insight into my situation, some tips, or best of all a Wiring Diagram of the Cluster/Dimming areas of the car, that would be great. Thanks for reading, and I really hope to hear back so I can finally drive my car at night.
