99 cavalier z24 odometer is all scrambled

The odometer lights still work, but about 2 years ago the numbers randomly got all scrambled.. certain parts of them are really dim and some are bright but they dont read clear. So i have no idea how many miles are on my car right now.. the thing is, my car is in the shop right now getting a remanufactured pontiac engine put in (my 2.4 got rod knock) and I need to know when my car gets to 500 miles in order to change the oil (breaking in the engine). I am so broke right now, and this engine + labor is costing me $2500 so Im hoping that there is a some what cheap way to fix my odometer or some other way around it :disappoin

you could swap the gauge cluster from another 99 or 98 1/2. But you will still need to know the milage off the other cluster in case you ever sell it, so you don't get into trouble.

hi,

the digital odo is...unreliable. when hot, mine freaks out but comes back
later...

i see no way aroud it except replacement. have you tried the trip OD, press
once.

id much rather have rotary. :)

The mileage for the odo is stored in the pcm, so if you change the cluster the mileage shouldn't change.
