Question.......
My battery died and I needed a jump start yesterday on my 99 coupe. After I got her started again I recieved a "service column lock" on the computer. I had this recall fixed a while back. What is this ? It pops up every time I start the car now.

Sounds like a new battery is in order to me, too.

Hello Kodak, 
Greetings to you. And, in regards to your dilemma with the service column lock prompt on your DIC, I totally understand your frustration. In general, it has been discovered by GM Chevrolet Dealerships that a low battery fluctuation, a low charge, and/or, status, as well as, loose cable connections, may trip this very annoying, but, nonetheless, alerting "service column lock" prompt on your dash.
Therefore, it would behoove you to do the following: Firstly, if you have an o.e. Delco battery, do inspect all connections, and, re-tighten. Furthermore, inspect the o.e. battery for any leakage (they are notorious for this). Now, if the o.e. battery is intact, remove the cables for approx. thirty minutes to clear all recent memory of the service column lock prompt in you BCM. This alternative application should resolve the issue.
However, if the battery is failing, you should consider replacing the notorious o.e. unit with a fresh battery. Franky, I had the exact symptomology when a mechanic had allowed my battery (at the dealership, no less) to wane low. The service column lock prompt came right up. Finally, the dealer mechanic had to jump the battery. However, although the alternator was fine, the o.e. battery failed to hold a stable charge. The dealer mechanic had then even admitted that the o.e. batteries seem to fail even moreso, after being jumped. Therefore, because I was already aware of the o.e. battery failure, along with the historical leakage problems of the o.e. unit, I replaced it with an Optima battery which has provided 3 years of trouble free service since. Please feel free to PM me for any further feedback.
Best Wishes to You,
Eden
