Buick Instrument Panel Cluster Repair

One day I was driving our 2001 Buick Century Custom, and I noticed that the odometer wasn't lit up. At first I thought that a bulb was out, but this instrument panel cluster (IPC) is completely digital, so there are no bulbs in those locations. The odometer/tripometer is all LED segment displays. It wasn't until later I noticed that the transmission indicator was also unlit. This can be dangerous if you think you are in park and are actually in reverse and let off of the brake. My wife and I kind of just dealt with the absence of indicators for a few months until I finally got around to fixing it.

Since there was no erratic behavior of any sort, I figured this was just a faulty discrete component somewhere and set out to look for it. If certain parts of your IPC are not illuminated when they should be, there is a good chance that this is what's wrong with it. I have found lots of people who had or are having the exact same issue, and this procedure fixed them all!

While the odometer did not work, did the mileage still increase or was it the same mileage as when it went out?

The mileage did increase correctly. The odometer itself is just a display in these newer digital systems. It doesn't hold any actually information, it just displays what the circuitry tells it to do. I don't know what part of the computer system is responsible for counting the mileage, but this has nothing to do with that.
