My gauges are not reading correctly. i dont know how much gas i have or how fast i am going. the only guage that works is the RPM reader. sometimes they will be in one spot then i will turn the car off and when i turn it back on they move. my speedometer is facing south?? i dont want to take my ca somewhere and be ripped off....
This kind of a pain the **** the dealer sells a cluster for about 350 then they turn around and charge to program it (60 to 80) dollars if you choose to buy a used one it could do the same thing shortly after you get it i am getting ready to replace a 2005 cavalier cluster that only has 33000 miles on it and i have another 2005 with 83000 miles with the same prob. so come to believe it is a age prob and not the use of it. i say pay the big money if you are going to keep car at least it will have a warranty

The odometer "error" is usually a BCM (body control module) problem, not the instrument panel. All the electrical signals you have lost all go to the BCM before going to the instrument panel.
It could be a simple connector problem.
instrument cluster is just for monitoring. but on modern cars there can be integrated circuits to calculate the actual amount of fuel inside tank. so sender sends signals and dashboard decodes it and show the amount on gauge.
which car do you have? if it is a later model with such system you may need to reset related software to match with new sender unit on pump or floater. (dealer can do this for you)
for example if you have a new daylight driving lights(LKM) controller on new BMW's if you replace it with a new one you need to code it to match with your car. if not it wont operate correctly.,
But there is an exeption. when sockets are broken or connections are wrong, fuel and temp gauges act erratic. they jump, pulsate or dont work at all. before replacing anything more be sure that sender unit or whole asembly is the correct part for your car. second be sure that connection has been done correctly.
There is a fuse for the instrument under the dash on the drivers side, if the fuse is good. Then give the dash a hit with your close fist right over the instrument panel, sometimes that brings it back to life. It's common for the wire harness clip on the instrument panel circuit board solder goes bad and need to be re soldered, the heat of the current after a few years will melt the solder and the clip comes loose and needs to be re solder back in place. Just remove the instrument panel from the dash, disconnect the wire harness and remove the circuit board and solder the clip back in place. Good luck and hope this helps. be glad to help.
