all doors are closed, all lights appear to be off, the security system doesn't "beep" the horn when activated. the dome lights shut-off quickly/abruptly when security is set...they used to dim , then shut-off. I suspect a switch is set wrong...I just can't find it. suggestions?

i think you have an issue with the bcm. you need someone with a scanner that can read the bcm codes and view the data stream.

this is beyond doing at home unless you have a scan tool.
