Posted question and only got a couple of answers on 2nd gen tech part of the forum. Had a issue with alarm going off for no reason. One night I looked out and all lights were on, headlights, interior lights, no alarm. Drove the vehicle the next day and the seat belt light was on constantly. ABS light came on then went off. Next day security light was on (not blinking). Changed out the ignition switch. Will start and immediately stall. No interior lights. No gas gauge. Other gauges work. Radio works. Tried re-learn process but security light is on (never blinks). Wish I could get rid of the alarm system altogether and make the Blazer reliable. Otherwise I guess I will just get rid of it.
