My temp gauge, fuel gauge, & their back lights are malfunctioning. This followed the light on the left side of my radio display going out. Are these problems connected or individual problems. .

The gauges move during ignition but are incorrect.

Back lights don't come on at all.

Any hints will be greatly appreciated. :?

What model and year is your car?

Please add that to your signature under profile as well.

It'* a 2004 bonneville SE V-6

So, it'* just the backlights for those gauges (discounting the radio)? What are they reading? Did this all happen at one time, or over a period of time?

Your car must have rolled off the assembly line right after mine. I'll be watching this thread closely.

for as cheap as the instrument clusters are on ebay (around $50), I'd just get a new one. You have some weird problems.

Of course there'* the issue with reprogramming the mileage... stored in the PCM but maintained in the cluster too.

simply swap out the mileage circuit boards on the back of the cluster

That'* all I gotta do?!? Dude, you rock! <runs off to eBay>

Carefully though. Notice the four corners on the PCB? They seem to have a locking post that holds the smaller PCB onto the larger one. You dont want to break anything.
