2005 Gauge cluster just died

[custodian]

2005 GT the gauge cluster has ceased working with the exception of the boost gauge (pretty sure this one must be mechanical), all other gauges are non responsive. Illumination is working on all gauges. Also, check gauge warning indicator, door ajar warning indictor and check engine warning indicator are on and will not turn off while driving car.
Car starts and runs fine. I have read that this is not an isolated problem and that several cars have experienced this problem. Any insight into this problem will be greatly appreciated.

Check you battery and battery ground bolt.

It would be unusual for several of the gauges to quit simultaneously due to internal problems. I agree that the battery or battery ground cable are the most likely suspects.

Make sure your front trunk and rear clamshell are closed. Do your wipers work only on high?

How old is the battery?

 

[JOETWINT]

Most likely the battery or ground as others have said....

Make sure it's the right type of battery too. We've seen all sorts of weird behaviour when people put a conventional lead acid battery in place of the AGM type. BTW none of the gauges are mechanical.

Mine did this the other day, but boost went out too. Just a simple power cycle of the key resolved my issue. I’ll be watching this thread closely as I feel it will probably happen again.

I agree, mine stopped working when the battery ran down but after a full charge was just fine again. Hope you are as lucky

And we would greatly appreciate an update from you.

If recharging the battery and cleaning the connections and restarting doesn't do the trick, then it gets more complicated. There is a module that sends the signals to the gauges that may be bad. The boost gauge does not directly read a mechanical or pressure signal. It also takes a signal from the module, so it's interesting that it still works and the others do not. These gauges do not read directly from sensors but have an intermediary box that does some kind of signal translation, because they have electric stepper motors inside them that drive the needles, not an analog coil and spring. Do write back with the results of your tests.

Guys, have I mistakenly been using non AGM batteries? Other than them dying after 2 years, I haven't had issues. Wish I had known that AGM was a necessity.

 

[fjpikul]

It is not a necessity. There aren't many batteries that fit.

Sorry for delay in answering, medical issues. Everything is closed and the wipers work, intermediate, low and high.

Sorry for no update, medical issue. Still no progress with gauges. Have tried all recommendations, but will still keep trying.
