Hi, these are the things that don't work in my car's instrument panel: speedometer, temp. gauge and gasoline gauge. odometer is fine...the sticks of those three gauges remain still while the car is on and moving. What is it that needs to be changed?? thanks in advance

Take the instrument cluster out and disconnect and reconnect all connectors, clean if necessary.

use a code reader to tell u where b the problem

It sounds like a connector cable is not connected to the instrument cluster. Has the instrument cluster been removed from the car recently. Too many problems for it to be a burned fuse; but still good to check just in case you have several burned fuses.
