1999 Pontiac Montana: console temperature MPG compass etc. failed


Posted on Feb 5, 2014

A 1999 Pontiac Montana. The information console that shows temperature, MPG, compass, etc. failed off and on for a few days before finally dying. At the same time, the radio display failed. The radio works just fine. The display can be read if you shine a light on it or if the sun hits it just right. I went to the dealer to have the console repaired. They said it was fine - and it was again but only lasted one day.

The cost to replace it is over $400 with parts and labor. I suspect that the console was reset when they plugged the electrical into their computer system. What do you recommend for the console and could the radio be related I am wondering if the Information Console (call the Driver Information Center) is having the same failure as the radio - that is - it is working but there is just no lighting on it. I have noticed that the same circuit is being used to drive the displays for both the radio and the DIC. Here are the schematics with that circuit highlighted in each. What I would do is check out that dimming connection coming from the dimmer, which is near the headlight switch, and see if you can make it change by moving the dimmer wheel.
