Odometer stuck at 999999

[bizarre179]

Well my g/f's alero started reading 999999 on the odometer yesterday. The car has around 90,000 not 1,000,000. I checked all fuses and everything like that and I come up with nothing. Also, I have never modified the cluster or anything else of the sort in her car. What do you guys think is the issue?

lol tell the newspapers u got a car 1mil miles

[Naich]

teh longest running alero evar!

but sorry, I really have no idea what can cause something like this.

[Nate's Alero]

if it was, it cant be a 3400 :lol:

shorted cluster? try a new one

[shiny alero]

kick the sh*t out of it :)

[Nate's Alero]

kick the sh*t out of it :)

ill make sure of that.

[jayson_waltz]

your cluster must have went bad

[AleroDrime]

gotta be an internal short but recheck everysingle fuse, i got two clusters for sale, you'd have to pay a dealer to check cars computer and make them read the right miles

[Nate's Alero]

BCM gone bad maybe? i know mileage is stored in the cluster as well as the BCM

[zzyzzx]

What did the factory service manual say when you checked it?

I tried to do a little research on it, but couldn't come up with anything..... Very interesting issue you have there... Does everything else work properly?

[bizarre179]

Everything else works fine including all the lights for the cluster and gauges. Its mind bottling.

*boggling.


i'd say a short in the bcm. pop that out (its against the firewall, under the glove box) and see if its wet.

oh noes if it is, windshield leak!

i forget the PN, but there is a fix

[bizarre179]

No it is bottling, like when your mind is in a bottle, ya know?

Anyways, I will check the bcm.

[cherrington17]

your mind is put in a bottle because of this?? :lol: weird

[Afugy]

[AleroDrime]

I was wondering about that one also.

[99alerogirl]

im catching it from all sides this month i swear

really? so you're a catcher? ;)

[Bad99Olds]

You and your mother have something in common :)

[pimpalero2003]

Any one you know have an alero if so plug there's in and see what it does if it's does 99999 thing it's your bcm if it doesn't it's the cluster.

[bizarre179]

Update! I went to go turn my car on yesterday and it read 92,920 which is the actual mileage. The only problem is that I have driven atleast 20 miles and it hasn't changed. The trip DOES work!

I am gonna try to swap it out with jeenysrider later today maybe to see if it is the cluster.

good luck 2 ya

[bizarre179]

For some reason, it now works. Yesterday my radio was coming on and off. I thought it was a short but didnt have time to look at it. Then last night the car wouldn't start because the neg. terminal on my battery is kinda stripped. Pushed it in and started it up, and now everything works...

Kinda odd.

[jayson_waltz]

the batt terminal could have been your whole problem actually. cars act weird when they don't get consistent power
