Answer
Hello,

Your guessing just like I am without knowing the year or model. First of all, I would put no credence in what a parts store guy saying he never saw this before, and I would be willing to bet there are many things he has not seen. He is a parts store guy, not a factory technician!

Man, I hawk this site so much, but you really need to go there-http://www.alldata.com, pay the $30 to be a member and download the service manual for your car. This is a factory manual that will guide you through any problem with diagnostic flow charts. The down load is good for a year. It takes the guesswork out of this problem and future problems. This is where I go when I need information on a vehicle.

Good Luck!


If my answer assisted you, please rate it. Thanks

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
