Question about 2003 Chevrolet Tahoe

1 Answer

Gauges and windows loses power.

Sometimes when driving the gauges and the windows loose power. Im thinking its only when I turn on the a/c for about 20 minutes or so because it stops working to have to turn the car off and then turn it back on. The engine stays on and the radio still works when I lose power to everything else. Any suggestions?

You need to look behind the fuse panel and make sure all connectors are firmly seated in their recepticles. You've got a marginal connection somewhere.

Check your battery connections to see if they ae clean and tight. Check all the ground wires in the engine compartmen to see if any is loose. Then check under the dashboard ror any loose ground wire connecting to metal points on the frame of the dashboard. You probably have a loose ground somewhere that is intermittently losing electrical contact....good luck!

1999 dodge caravan gauges are all mest up


Could be different problems.
The cluster issue could be a problem in the printed circuit board inside the cluster.
The cooling fan problem could be low coolant, a blown fuse, a faulty temp sensor, fan motor, or relay.

1991 chevy van, gauges dont work at all what should i check besides fuses ?


Some of the older Chevy trucks (and vans) had problems with the connector on the back of the instrument cluster getting loose and losing power. Sometimes you can verify that this is being caused by a loose connector by banging on top of the dash a few times. If the gauges start working, then you need to remove the instrument cluster and repair it. Usually, the solder joints that connect the connector to the circuit board crack and come loose. It can be fixed with some silver solder and a soldering pencil.

take a look at the dash ground wire located next to the right of ebrake release handle. if the bole holding the ground wire is loose, which was quite common it will cause all kinds of feed back problems, like described in the comments section to your question.

A faulty temperature sending unit. It should be located on or near the thermostat housing. If any of your gauges reads zero, the check gauges light will come on. Sometimes even if the fuel gauge gets too low, it will trigger the light. It may be the connection at the sending unit. It may have become loose so wiggle it and make sure it is securely connected to the sending unit. If the temp. gauge needle pegs at the top of the gauge, it means the sending unit has grounded out and is faulty. If it jumps, reads off or not at all it could be a faulty sender or a bad connection.

Gauges turning off


Hi,

  1. I would seem that your electrical system needs a thorough look over. Suspect would be connectors (either corroded, loose or burned), fuses and relays. Specifically:
  2. windows don't go down - check the fuse, switch motor;
  3. the gauges all turn off when the brakes are pushes - check that the gauges IGN B+12 is not intermittent (loose connector from IGN switch);
  4. the gauges turn off then back on when the headlights are turned on - same probable cause (loose IGN B+12);
  5. the brake lights don't work - faulty brake switch, burned out bulbs, loose/no +12 sup[ply to switch.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
