Make sure all wires to the transmission are connected. From there, change out the VSS (Vehicle Speed Sensor) On the transmission's tailshaft. If it's still not working, you need to open up the dash and make sure it's all well connected.

you may need a car electrician as these things need troubleshooting.the only thing you can do is by checking all fuses however if other gauges and indicator lights are working then the fuse for the inst. cluster is ok.the speedometer has a sensor installed on the transmission while the odometer gets signal from the ECU so these two problems need separate solution

Hello.
What sounds like happened is that the instrument cluster fuse sounds like its burnt out. Otherwise the wires on the back of them both may have been knocked out. Very simple fix if its the fuse, if not, pull the cluster out and check the wiring. Hope this helps!

Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

INSPECT YOUR SPEEDO CABLE, IS IT BROKEN?????, IF NOT THEN IT'S YOUR SPEEDO HEAD BROKEN....IF YOURS IS ELECTRONIC THEN CHECK THE SENSOR AT THE TRANS "VSS" SENSOR...WITH OUT TEST EQUIP. JUST REPLACE IT AND RETEST.....gl

Since your speedometers work, the problem is in the gearing to the trip and mileage odometers. Simple problem, major pain to fix but, remove instrument cluster - you'll have to remove speedo cable to get it out. Use the old Mark I eyeball to check for broken parts. Might even have to drop steering column - disconnect air bag first!

these can also be caused by a bad alternator

not simple, it could be the instrument cluster or the speed sensor/cable
