Question about Cars & Trucks
Fuel gauge not working
Most likely the sending unit in the tank, but you can have wiring problems, BCM problems, or even dashboard problems.
Hard to just give an answer, diagnosis of the systems is needed.

SOURCE: 97 cadillac deville fuel gauge.
Not a current owner, but knowing Cadillac, that may be the way they meant for you to think of the fuel. How many miles till refill. Maybe that made it easier to swallow the high priced, too frequent fill-ups! I'll ask my friend, he's got a '99.

hello. it should be located under your car on a line that's coming off your fuel tank and yes you can do this your self very easy to do ,you'll need a few box/open ended wrenches that's it you'll need to check the fitting or the nut on each side of the filter to see what the sizes are,befor removing the filter you'll want to take off your gas cap and remove your neg battery cable ,not when you find the filter it'll have nut on each side all you have to do it loosen them but make sure that you don't break the fuel line or kink it and after you have both sides loose then just finish turning them off and there you go the filter is off, nope no removing the gas tank some newer models you do and the filter is attached to your fuel pump and don't need replaced but for your car and year you wont need to remove the tank. good luck

i had the same problem in my 91 deville but the fuel gauge was intermittent at first, working most of the time then eventually it quit working all together, i also replaced my ignition switch thinking that was the issue but what actually happened is the fuel gauge shorted out the 16 volt supply from the bcm (body control module) which also feeds the ac and in my case the digital speedometer. your speedo probably isnt digital, but if you unplug the fuel gauge from the harness your ac gauge should come back on or vise versus unplug your ac and the fuel gauge should come back on right now im trying to locate fuel gauge. i hope this info is helpful to you, all you need to remove the gauge is 1/4 inch drive rachet and 7mm socket and a phillips screwdriver (#1) for the trim
