Acura TL odometer trip meter not working Questions ... - Fixya

this sounds like a bad speedometer cluster, you stated everything else works so i assume the speedometer is working and just the odometer and trip stopped working and so the speedometer will need replacing. good day.

news doesnt sound good> your instrument cluster will need replaced and the odometer set by the dealer.

If the speedometer is working but not the odometer it's in the speedometer it's self. replacing the speedometer cluster is the easiest their available on ebay or your local salvage yard.
what happens is the trip odometer wears and sticks, theres a small motor on a circuit board with a plastic sun gear, inside the speedometer housing. it drives both the odometer and the trip odo
the teeth strip off the sun gear and odometer stops.

check your speedo cable it runs from your transmission to the back of your gauge cluster. its probleby broken or disconnected

you have a problem with your speed sensor, you need to check or replace it.

The problem is going to be a worn or broken odometer gear. You can purchase the gear at odometergears.com for $29.00 with the shipping. Follow their how to repair on the Mustang to help in the repair. I believe you will have just the worm gear to replace.

sit in the drivers seat close the door. with the key off hold the trip odometer button in then while holding the button in turn the key on. if done correctly this will put the MIC (mechanical instrument cluster) into a self test. if the speedometer does not move like the rest of the gauges during this test the MIC must be replaced. if the speedometer does move it is likely your problem will be fixed, however, if the speedometer does move but it does not start working properly then further diagnostic will be needed.

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!

speedomenter cable may be broke or speed gear may be bad
