The dreaded security light problem....so persavisve in the gm post. what a pain this thing is!!! Still havent fixed mine...I have been doing the 10 min wait, for a while now...I hear it cost upwards of $400.00 to fix by replacing the tumbler and chances are...its just going to do it again...and gm will not recall! I have found a way of by passing it here on this site...the ole cut the yellow wire and toggle switch it....My question is? I will do that but has anyone experienced any issues with bypassing it in this way. Will it work? or when I cut the yellow wire with the car running will it die and will i be able to start it again or will I be Srew#@D after I cut it and have to tow it and pay gm the fortune they want to fix it anyway...any problems with this bypass or will it work? fem.
