Speed,rpm,gas,odometer gauges not working

That's why you don't let you husband work on your car ! Unless he does it for a living .. For MPH there is a VSS - vehicle speed sensor , for the gas there is a sending unit in the fuel tank, for the temp. gauge there is a temp. sensor located in coolant stream on the engine .You more then likely need to have you instrument cluster repaired . GM had a problem with step motors inside the instrument cluster . A step motor is what controls the individual gauge. The sensors are all inputs to the PCM - powertrain control module (engine computer ) .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to C or below if:
?€¢
The PCM detects a malfunction in the engine coolant temperature sensor circuit.

?€¢
The IPC detects a loss of class 2 communications with the PCM.

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The PCM detects a malfunction in the fuel level sensor circuit.

?€¢
The IPC detects a loss of class 2 communications with the PCM.

When the fuel level is less than 14% (84ohms), the low fuel indicator illuminates.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily press the trip select/reset switch in order to toggle between the season odometer and the trip odometer. Press the trip select/reset switch for greater than 1.5 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed information from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected.
PRNDL Display
The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display shall flash all gear positions if:
?€¢
The PCM detects a malfunction in the transmission range switch circuit.

?€¢
The IPC detects a loss of class 2 communications with the PCM.

Speedometer
The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses per mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 mph (0 kph) if a malfunction in the vehicle speed sensor circuit exists.
Tachometer
The IPC displays the engine speed as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine speed. The tachometer will default to 0 rpm if:
?€¢
The PCM detects a malfunction in the engine speed sensor circuit.

?€¢
The IPC detects a loss of class 2 communications with the PCM.

Anti-theft system problem . repair shop

check you speedo sencer maybe replace it this will fix your problem

I would say that the speedometer and odometer probably a bad speed sensor. They are symbiotic so if the speedometer fails, the odometer will fail as well. If the needle on the gas gauge lies dead on the "E" all the time, I would blame a faulty gas tank sending unit and replace the unit. However, removing the tank out of the car is required for the repair. If the gauge is pegged on "F" at the top of the gauge when the key and/or ignition are on/running and it lies dead only when the car is off, then somewhere there is a short to ground either at the origin, at the destination or along the path of the signal. Still, chances are the sending unit is bad. As for the window, check the fuses in the fuse panel. If they are good then I think you should be confident of a faulty window relay causing the problem.

My gas guage, speed odometer and tempiture does not work
The speed odometre is reading 9999999 what should i do

Have the computer checked

needs a backlight bulb this can be easily replaced by removing the cluster.

the odometer backlight bulb is replacable but the illimunation bulbs for the other gages are not.

erique000, on Feb 06, 2009 you posted a comment about your odometer and gas gauge stopped working. Did you ever find the problem. I have a 2001 sl1 and the same thing occured but also the rpm gauge and the speedometer registered nothing. They all just sit at e or 0. Approx 20 miles later the car died. It will still turn over, but won't start. If you have a chance, please respond to [email protected]
Thanks, Tom.

Tighten the battery connections with a wrench, not pliers!
Loose battery problems are a common problem with GM side mount terminals. They need to be very tight to work right.

Happened to me before too! No power, no lights, no radio, no crank.
