Default Cluster of Exterior Lights Out, Help Please!

Hello,
The other night I had three lights all go out at the same time. They are the driver side: Rear park light [this light doubles as a brake light], rear red signal light, and yellow signal light. Note that all these lights are on the driver side of the H2.

I checked all the fuses and all fuses were good. I did find a wire shorted out on the frame that runs from the license light [from spare tire carrier] and is spliced into another wire that attached into a connector. The wire has since been fixed as to not short out any longer against the frame, however the three lights still do not work.

Has this happened to you before? Are there any modules that I can check that may be causing this issue?

Been trying to look through in the 2003 SM but afraid I am not having much luck. Do the emergency flashers work at all ?

Body Control Module is in the drivers side dash about mid way up, just a FYI.

I can, if you want, take some pics of the 2003 wiring pages for the lights and post them if that will help ?

Just took a "few" and will need a little bit to post them on Photo Bucket so they are "readable".

Shall return, Ed

How do I tell if the BCM is defective and the cause?

Sorry Mods for the sizes but needed them to be readable for JMV1210...

No special order due to how they were loaded on Photo Bucket.

Hope they help find the problem.

Ed

P.S. Only allowed 10 pics so I will load the last three in next post...

P.S.S. Notice while setting this up you wanted to know about the BCM, you will need to have it scanned for codes sorry to say....and that has to be dome buy a dealer with a Scan II scanner. Parts stores cannot scan body modules that I am aware of and I do not remember if the Hypertech I got will even scan body codes but I think it was how I found out about my heated seats not working. Sorry for the vauge answer on that. Some of the pics talk about the BCM by the way.
