Not sure what is causing this problem. Flashers and Dash lights flash constantly while the car is running. Car seems to run fine and all the systems seem to be working ok, but I think something is definately out of whack. Currently deployed to IRAQ and home on R&R Leave. Wife says the car lost power and was barely driveable 10 months ago so it was parked and not driven until needed a month ago. Was thinking something is wrong with the computer or ECM but not sure. I've never seen this before on any car I've owned or worked on. Any help would be great.

Check under the dash for an aftermarket alarm system. Sometimes they tap into the dash lights and turn lights for arm/disarm warning. If you find one, just reconnect any wires they interrupted with the alarm wires and unplug any that they tapped into

Car has no aftermarket alarm, however, it does have Gm's pass key or VAT's system everything on the car is factory. It stopped flashing when I took my kid to school this morning, but when I shut it off and started it back up it came back. Car seems to runn fine, even tried using the other key same problem. The remote keyless entry pads don't work anymore now for some reason either. Any ideas?

Which 88 is it? I need to look up the wiring diagram. Try this, just to see if it helps

GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

Your first suggestion proved to be right on. Got to looking at the keypad for the keyless entry and while not marked with an aftermarket company name it wasn't marked as GM either. Initailly wasn't able to find a computer or control box for it, but I was only looking under the dash. Took it down to Edmond Auto electric and had him trace it for me. Turns out it was under the hood in a very obscure location. Removed it. Problem solved. Thanks for the help
