Hi, i have a '99 coupe with a manual trans. I brought the car to the dealer on a trailer a little less than 2 years ago (june 2009) for the all too common "service column lock" and some warranty work under my extended warranty. The column never locked, but i had the pull key and service column lock messages and the fuel was cutting off at the 1.5-2 mph mark. The invoice claims they replaced the shorted relay with relay and harness part #19244028 harness k. Long story short, i have a fully charged battery with tight connections, a pull key for 10sec message, then the service column lock message, and again i cant accelerate past 1.5-2 mph. The car will also shut down if the wheel is turned to the locks either direction (the column is not locked) I have access to GM Service Information and found the car has been repaired on more than one occasion for this issue. I'm wondering if the aftermarket bypass will solve the problem. I was not able to find a real answer with my symptoms and i hate the thought of the dealer! I'm an ASE certified mechanic and the ONLY reason i let anybody touch my car besides me is because i had the warranty and wanted to save some money. Since that didnt work, and they charged me for it anyway (warranty wouldnt cover it) just to have the issue again less than 2 years later, i WILL fix this MYSELF this time. If the bypass will remove the message and get me running again, who has the most reliable unit?I've heard most use the thunder racing or the corvettes of houston unit. Any Suggestions are greatly appreciated!
