Odometer and trip meter not working.
The odometer and trip meter have stopped working and I am getting ready to try and fix it and I am wondering where I should start. Both my tachometer and speedometer work perfectly fine. The only gauge that doesn’t work is the oil pressure gauge which I hope a new sending unit will fix. I just don’t want to go tearing stuff apart without some peoples input. Thanks!

Re: Odometer and trip meter not working.
sounds like the gears broke in the cluster to me. its pretty easy to replace, therye just plastic gears that drive it. you can find replacements on ebay. make sure you dont interchange the gauge needles when you take them off, itll mess up the readings for some reason
