My cars gauges just stopped working last weekend.

check connections wiring and for proper install and no fuse

Without doing some electrical testing who can say . Your best bet , take it to a qualified repair shop .

I would start with the ignition switch.

i'd change the engine temperature sender unit , or just disconnect it for a while and see if the gauge symptoms disappear , if they do then change the temp sender unit,if the symptoms remain i'd say get the OBD codes read as may have a faulty dash component

Restriction in the exhaust can cause this. Test with a vacuum gauge normal 60 mph readings around 14-18 hg. in depending on throttle position once power loss starts if reading goes to zero restriction is present. then use of a infra-red thermal heat gun you can locate the restriction. hot to cold at plugged stop.

check out rockauto.com i have found most all parts for my saturn vue 04 v6 3.5l fi. go to the parts catalog and select ur year, make, model, and engine.

The plug at the back of the panel has come lose.Remove the dash panel and push plug on firmly.Hope that was helpfull.

can you tell me why does the gas thing does not go up when i fill up

the odometer backlight bulb is replacable but the illimunation bulbs for the other gages are not.

they are full of it, u should show oil pressure as soon as the engine starts, this may be a sticky guage or a sender but that advice they gave u is bull, that is for sure, I am a GM technician.
