Just started this morning.



There's only three gauges on this thing besides 'Fuel' and they all look like they're showing the usual values.



Anybody know what triggers a "Check Gauges" light?

I have never seen a "Check Gauge" Light...Maybe a Burnt Out Bulb??...Also Steve We all get "Low Fuel" Light Warning when we get below a certin point...But OP would like to know what would cause a "Check Gauge" Light....Pete when you do find out..Let us all know Thanks and good luck Iron

No on a 98 low fuel will set off a check gauges light..Also will low voltage, low oil pressure ...Thats what its telling you to do is check the gauges.....If have a bad fuel level sensor the CHECK GAUGES light will come on intermittently....Funny I have a 98 Burb and I don't have a low fuel light...As a matter of fact that is what was wrong with mine...Hmmmm dont know mine might be alien but if your trying to make me look like a stupidass ya need to do your homework....

Per Steve Cook:

I'm starting to suspect something to do with the cooling sys.

Going through a toll gate yesterday, I caught it in the act: the thermo was maxed.

Preceeding that was about 2.5 hours crawling in a traffic jam, a 30-minuite dinner break, and about 20 minutes at a steady 60-65 mph.

After pulling out of the gate and crossing a bridge at abour 45 mph, I could actually see the gauge falling until it came to rest at the usual temp.

Per Ironworker:

Slow leak at the heater control valve.
