the last couple of mornings when i have started my car the rpm and the speedometer needle would shoot way up. my tripometer would also reset to zero. i thought this was odd but figured maybe since its been cold here (florida) that was the reason. well i went to start it this morning and nothing happened...wouldnt even turn over. the battery is brand new i just had it put in at the end of october. any ideas?? thanks in advance!

The cluster will do that when its cold out, because your cluster is the old style that doesnt have the updated non-volitile memeory chip in it. that is normal for these cars, the only way to fix that is to replaced the cluster. Mine does it everyday in ohio from september to may. no big deal. The no start problem is not related. check battery cables and the new battery, even tho its new doesnt mean its good. try to jump start it and see what happens. Let me know if I can help anymore.

With low voltage the '99 cars do that if the cluster hasn't been changed, there's even a TSB on it. Double check the battery/connections first.

okkkkk listen....this is happening to me right now, trip resets needles shoot across...blah blah....its the alternator....just change it

Um, no Actually its a chip inside the cluster that looses memory when temps get colder outside. I have the TSB in hand directly from GM stating this problem, not to mention I have fixed several at work for this. Now if your alternator sucks it will contribute because of lower voltage in the system, but still wont repair it when the weather gets cold.

Here's the TSB, doesn't mention the gauge sweep but usually happens at the same time. http://home.earthlink.net/~cetera/pics/aug99tsb.jpg

Edit: What CCA is the battery they put in? Should be a 690 minimum for the LS1 according to my helms.

i replaced the alternator yesterday. it wasnt too bad, the toughtest part was getting the bolt on the back of the alternator out. hopefully that was my only problem. so we'll see how it works out. thanks for ya'lls help!

Some people just dont listen. I hope that alternator was cheap.

i took in everyone's advice, but when i went to sears to have the battery tested, they also tested the alternator and that was bad. thanks for your help though!
