98 Camaro Convertible no courtesy lamps

I just bought a used 98 Camaro Conv. V6 for my daughter.  No interior lights come on when you open a door.  It has the security system but is programmed for "Exit Lighting" & "Delayed Illumination" which is the default (Mode 4).  I checked it per the manual.  I have 12 volts coming to both leads of the light which is located in the rear side panel by the speaker.  I also hooked the light directly to the battery and it worked fine.  The other side is the same.  I assume when you open one of the doors, the door pin is suppose to ground one side of the circuit.  I took both door pins out and tested their continuity and they are working fine.  I was wondering if there is a controller (BCM) that has gone bad, maybe the chime box located behind the glove box??  It has a lot of wires running to it.  My map lights work only with the switches on the mirror.  The owners manual says the map lights are suppose to come on when you open the door.  The interior lights do not come on when you rotate the dimmer wheel all the way up also.  The dimmer does work with the dash lights.  When you open either door, there is no chime nor no lights.  I have seen this problem with other convertibles posted on other forums.  The chime does work if the headlights are on and the door is opened.  Anyone know of a fix?

I think my problem is the BCM.  I left all 3 of the harnesses unplugged from the BCM.  At the Black harness, I jumpered the Orange (battery 12 volts) wire with the Blue/White (courtesy light) with a 20 amp fuse in-between (same as the courtesy fuse).  In the large light blue harness, I jumpered the White wire (D1) to ground.  Sweet!  The courtesy lights came on!  I then jumpered the White wire (D1) with the Grey/Black (D11 driver door pin) and the lights came on when I opened the driver door.  Ditto for the passenger door pin (BLACK/ White D12) and dimmer (grey C7) wire.  I plugged the 3 harnesses into the BCM and the lights did not work again.  Now that I know I did not have a short, I jumpered the wires as described above in the light blue harness, but this time with all of the harnesses pluged into the BCM and the courtesy lights worked.  So I'm 99% sure the BCM is bad.  How much you ask?  Around $200.  I think my extended warranty I bought from the dealer will cover it.  It lists electronic control module as a covered component.

Just got it back yesterday. It was the Body Control Module (BCM).  The BCM is around $200. Since we just bought the car, the dealer paid for it. I noticed that Chevy had changed the part number from the original.
