You might have a bad ground. According to my Haynes manual's wiring diagram, both gauges share the same ground and typically that is "located on the left side of the instrument panel", wherever that is. Sorry I can't be more specific about the location. While it may not be true on your vehicle (the wiring diagram states "typical late model" in its description), my wiring diagram says that the ground wire is Brown (BR). You might try locating that wire and track it to its attachment point. You also might try tapping into it and using a continuity tester and ground out the wire to metal (there's plenty of grounding points under there). Make sure the ignition key is off!! There might be a bad ground wire closer to the meters than the attachment point. Hope this is helpful. Allow plenty of time if you're going to investigate this yourself. Do you have other gauges? Do they work? I think that all of the gauges are ganged through the same fuse (but not through the same ground wire). You might consider checking the fuse to ensure that it's OK. Your owners manual that came with the truck will tell you which fuse is it. If there are other things on the same fuse and they work, it's not the fuse. I hope that this is helpful.

Only my fuel gage dont work


Check all your fuses and make sure you are getting power to the gauge. If not you have to change the sensor in the tank to make it work. Here http://www.wholesalesensors.com/air~fuel~ratio~sensor.html you can necessary details about the sensor which helps to work the fuel gauge.

My 1991 mr2 toyota temp gauge dont work i install new temp swich and still dont work


Temp Gauge wire may be open circuit. Operation can be checked by Shorting connection to Temp Sender to engine. If the circuit is OK the Gauge should go up to Max.

My temp gauge and fuel gauge stopped working on my 1988 toyota pickup all of a sudden, what do you think?


Check all fuses with a test light. If all good, you will need to diagnose each circuit. Look for the temperature sensor, disconnect connector, ground test light and touch wire. Check to see if the gauge move. If it does, you will need a new sensor. Basically the test is the same for fuel gauge. Disconnect connector at the fuel tank and touch contact and see if gauge move. If it does, the sending more than likely is at fault. Make sure you test each wire as there will be a few. Use proper jack stands anytime you work under a car! Let me know your progress.

My heat gauge quit working on my '91 Toyota 6cyl. engine. Is there a fuse for this? Where would I find it if so?


Is the Fuel gauge reading properly?
If so, the fuse is not blown; they are on the same circuit.

If the fuel gauge works, I would guess that you may have a bad temperature sending unit.

1993 chevy pickup 1500...started getting bad gas mileage temp. guage doesn't work


as far as the temp gauge goes...i have a 91 1500, i had the same problem. i replaced the temp sensor and it fixed the problem.

as far as the bad gas mileage... if you haven't already done so, perform a tune up; plugs, wires etc.
