Hello all.
I'm in a jam and hope i can get some help here. I own the 2002 L200 Saturn that just started to have Security display on the dash on and off. When the light comes on its accompany with a few other dash lights. Sometimes the car will start and stop and other times the car just run fine. Sometimes it will not start at all but after about 10 minutes or so of waiting and trying again it will start. When the Security light show and stays the AC compressor will come in and out of operation. This seem to happen more when the car is warm or weather is hot outside. I have attempted to reset the Passlock many times but didn't help. I have already replaced the Ignition Cylinder but still same issue. Any idea what else to go after? Any help will be appreciated.

 

Sounds like BCM (Body Control Module) is flaking out.

Wait to see what others think
