I backed out the bolt all the way. I am tracking down an open from the BCM to the driver door actuator.
look at the video

That bolts only holds the outer harness to the block... back the bolt out more then pull

You have to remove the lower column cover and the knee bolster
Then you have to remove the inner wiring harness connector
Then there are 2 bolts and a clip holding the fuse block in place

I think each half is C1 and C2, so what you are saying is back the bolt out more and pull C2 away from the other half C1, then I can test each half to see where the open is. I tested from A12(C2)on the BCM to "A" on the actuator connector and A7(C2) on the BCM to "B" on the driver side actuator connector. one showed continuity the other did not... so if I seperate the junction block i can test from C2 JUNCTION BLOCK B1 to "B" and junction block C2 B5 to "A", then JUNCTION BLOCK C1 B12 to BCM C2 A7 and C1 JUNC BLOCK
B8 to BCM C2 A12.. I wrote down which circuit had the open. The rest of your instructions are for removing C1 and the actual I/P junction block...will help greatly.
