My speedometer will not show the speed of my car while driving it how would i fix it i have looked in the book and can not find anything that will help me solve my problem.

its a super old car 1990s" or older with cable drive speedo
and most have the actual speedo bad.(guts)
I fixed losts in year 2000. using 2 used speedos and swapped guts to get one good one.
yes I dead 1997 sidekick, G16b. the speedo has needle and shaft and a spring and bushing
the silly bushing wears out, and the needles goes nuts.
the needle is magnetically coupled,
seen here, (mine)

I have shared this with many sidekick owners world wide.
there is no fix.for bushing, (hacks maybe)
there are no spares sold by maker here.(out of stock forever)
only buy used speedo cluster off fleabay ,works
warning there are 15+ speedos, most will not work (2door and 4 not the same, and county) just in North America. more world wide.
the transmission has different gearing and axles change this tool.
secret, speed P/N pulled out, cluster, bottom has the real part number.>> look here.
USA or canada, KPH or MPH. versions.

Ensure that you haven't recently changed to larger tires, changed your transmission or gotten involved in a rear-end crash, as these factors can all contribute to speedometer problems.

Check the gear at the transmission end of your speedometer cable to see if there's any damage caused. Purchase a new gear and change it if the part looks damaged.

Compare the speed of your car to the speed of other cars on the road while driving to see how far off your speedometer is. Take the car to a speedometer shop or someone who knows how to fix speedometer magnets to recharge the magnet.

One on the transmission on the rear driverside of the transmission is one that operates the speedometer, replace it.

Sure you can if a mechanic can do it so can you if you have the right tools and knowlege. First you need to know which one thers's one at each whell at the fround rear end housingf the rear rear end housing and the one in the side of the transfer case where the speedometer cable would'of connected on an older model and then theors three in the sides of the trans mission, Touque converter speed forward turbine speed output turbine speed. What proble are you trying to fix? the speedometer not working? Abs light on? Cheack engine light on? Cruise control not working? If the cruise control does work the speed senser is good and the check engine light will be on if the speed senser is'nt working. If the speed senser is'nt working the car will only take off in low and not shift to seecond or any higher gear as the computer doesn't know how fast the car is going. If the speedometer is'nt working and it does shift and cruise and the check engine light is'nt on then the speed senser is working but the speedometer is'nt if it is'nt and everything else is woring then as your driving hit the speedometer with your fist and see if it comes back on they can get stuck and i've fixed quite a few and they stayed fixed. On to wheel drive models with the rear wheels jacked off the ground safty I've run the car up to speed and trying wiggleing the wires and connectors till I wiggled the right thing till the speedometer came on ( including smacking the speedometer ) Just don't hit it too hard as it'll bust just like anything else.

then have ytour tech look at it.

it may be vehicle speed sensor, located on side of transmission, or loose connection to cluster

This is an electronic speedometer, nothing is user repairable, the circuit board fails and you get your problem, you will have to pull the speedo and send it out to an authorized GM repair station, they are all over the country, one company that does this is called SPEEDOTACH, LOOK THEM UP ON THE INTERNET.
