not directly... The tach gets its signal from the crankshaft sensor. the signal is processed by the computer where it determains spark timing, fuel ratio and other things. information is relayed via wires to the back of your insterment pannel, and are converted into readable units on your tach. Same with the odometer, it gets its signal from the computer via speed sensor. being you lost both functions on your pannel, i would suspect a faulty cluster.
My odometer stopped working about a month ago.
No, they stopped making saturns in 2009 I believe.
Funny thing about saturns, they don't have an "odometer cable" They use a magnetic pickup assembly, located in the rear of the transmission, just above the passanger side axle output. this sensor is connected directly to the engine computer. from the computer the signal then goes to your instrument panel and is converted into electricity to drive a small motor to turn the digits which you can see. if the odometer has stopped working, replace the speed sensor on the transmission, or your instrument panel has failed.
what can cause my speed odometer to stop working, it would work awhile, than stop, now not at all
If the odometer stopped working and the speedometer and cruise control still work, you have a bad odometer. It is part of the speedometer assembly so the whole thing will have to be replaced.
"The fuses are good." Well, your odometer certainly isn't.
IF ALL WINDOWS HAVE STOPPED OPERATING AT ONE TIME YOU MOST PROBABLY HAVE A FUSE PROBLEM. IF THEY HAVE NOT ALL STOPPED OPERATING OR THEY HAVE STOPPED OPERATING AT DIFFERENT TIMES YOU PROBABLY HAVE POWER MOTOR PROBLEMS.
More than likely, it sounds like your odometer cable has been disconnected or is failing. A new odometer cable can be picked up at any auto parts seller.
get it fixed
If your odometer/speedometer stopped working, then you must replace the "vehicle speed sensor" located on top of the differential if your have a manual transmission.
Check the speed sensor.
Because GM needed to consolidate and nobody wanted to purchase the Saturn brand, so they simply stopped making them.
