Gauges and Warning Lights Are Going Crazy

I have a 2008 Pontiac G5. The fuel, tach and speedometer gauges are going crazy, simultaneously bouncing around erratically. At the same time, the Power Steering, Low Fuel lights flash, sometimes losing my power steering. What should I check?

Hi there! I am having the same issue. It seems like every time that it rains a lot this happens. Check the battery though, the ground connection of my battery is wet every time this happen's. Check if the battery is damp or wet, that is usually what causes it for me. I am in the process of getting a cover for it, or putting electrical tape over it.

1. Air filter dirty
2. Bad engine ground connection.
3. Loose connection in the ignition system.
4. Faulty idle control system.
5. Faulty emissions or engine control system.
6. Fuel not reaching the injectors.

These are the 6 most common solutions. For yours, i would certainly be checking the engine ground cable, as your gauges are acting up too. Take it right off, clean the rust if there is any. Bend it back and forth every inch or so to see if there are any breaks or melted spots in it. Or, better yet, just throw it away and get a new one. Good luck, hope this helps.

SOURCE: 1996 3.1L Pontiac Grand AM all gauges went crazy

sometimes when the battery is too low the gages will go haywire.check you battery terminals for good conductivity and current levels. sounds like a low current problem.computer runs on 12 volts not 11 or 10. low current will give poor performance and bad electrical response.
try that first then look for shorts under the dash ie naked wires or burnt wires.
good luck.

If trans is still shifting its most likely a blown cluster fuse or bad cluster.If you have a check engine light & trans don't shift most likely blown trans fuse or trans vss (speedo) harness at right drive axle broken puple with white stripe wire or light green wire with black stripe

I have the same problem.. i installed a toggle switch for the fuse so at least I can reset it while driving.. its still a pain so Im thinking my next step will be to drill a hole through the plastic and put in a small metal post to stop the tach from going past 7

has anyone taken theirs into a shop?

99 camaro gauges going crazy


Chances are you could replace the cluster from a salvage yard replacement and it will likely fix the problem. There is a flexible circuit board affixed to the back and it probably is bad. It will be attached to your replacement cluster.
Should be able to replace in about an hour.

Hi, airbag deployment rarely causing damage to the wiring in the dash. The gauge cluster may of been damaged internally, but this usually shows up right away after repairs are done. I would check the connector on the PCM it is a cam lock design and if its been damaged or not closed properly it can cause crazy things to happen to the gauges. Good luck.

The warning lights started going on and off, all the gauges started going crazy. Then engine lost power and died. Towed it, put it on the charger and it started but would not stay running. One person said...


Most likely the alternator........ map sensor failure would bring up a check engine light and code not the crazy gauges and lights
hope this helps...Good Luck!
