Thanks guys. BCM didn't make it here yet. Should be in tomorrow im guessing. No security light or anything. Instrument cluster is completely dead. Only thing that works on the car is the under hood light and headlight and taillights when I switch them to on. I spoke with a tech that has a tech2 scan tool and I will get him to re program the BCM once I install it. Fuse box is tight and all grounds are good and clean. The starter wire is good. Wiring harness is good also. No blown fuses or relays. New key fob battery and car battery. Hopefully once I install the new BCM at least my cluster should come back and ask for key FOB.

Installed new BCM and no change. The 4 post that secure the fuse box are snug. Is that the post that ground the fuse box? If so im not getting continuity to ground on either one of those 4 post.

Just realized when I connect my battery post to the battery I can hear something wine in my dash. Almost like the sound of a fuel pump priming. My best guess is nav/radio. My power seats will work but my door locks and windows don't. Also my emergency flashers work but wont show in my cluster because my cluster is still dead. With my battery connected I checked for voltage at the PCM 15A fuse on BCM and im not getting voltage there. Not sure if I should be getting it there and if so when? I am getting battery voltage to my BCM from the red with black stripe wire and also the red with white stripe.

Did the BCM wiggle test with no change. I double checked my wiring harness and did find this. Which I thought for sure would fix my problem. I soldered and heat shrink these two wires but still nothing. Does anyone know if a bad key fob or security system would cause these symptoms? Any last resorts before I have to tow this to the dealership?

Went to the dealer today and all the service advisor could tell me was they had nothing for me yet. All they tell me is they cant communicate with any of my modules and need to test each module. Its been 4wks! starting to get ridiculous. GM service is awful.

They already tried a the new BCM and still couldn't communicate. This Saturday would be 6 weeks they had the car. I know the RCDLR sends a signal to the BCM then the BCM sends a signal the PCM. Its either of these 3 modules they just havnt been working on it. I talked to the tech yesterday and they told me they only work on it 1-2hrs here and there. Then I told them my opinion on that and how its been 5 weeks. Also said ill send it else where if they cant handle it or get forward progress on the car. So your car was acting the same way as mine? How did your problem start?
