Keep those retros for the tahoe!!

Yep. I'm now thinking of trading in the avy for a Tahoe. F all this troubleshooting.

Sorry to hear such bs. I would put some cheap headlights on and trade it in at this point.

 

[felixgun]

Yea I'm thinking about doing that actually.

I still think it's a simple fix.

That has all the wiring diagrams they will need. Remove what isn't working and wire in new. If the reverse signal is working on the trailer harness then jump that to the reverse lights.... Done.
Use interior trigger off of switch to trigger new relay patched into main harness in a pillar. Done.

Problems. Solved.

Well I talked to the actual shop and they said it's because of the HID's I had in my reverse lights in the tails. Apparently the amperage is around 7 and mine was around 40. It fried the wire going from the reverse lights in the tails to the BCM and also messed up the BCM. So they said I have to bring to the dealer and change out the wiring and the BCM and get it reflashed. Sucks so bad. Debating whether to fix it and sell it or trade it with the problem and let the dealer fix it and let him give me less for the vehicle...

 

[07Burb]

Wow that sucks at least they narrowed down the issue but frying the BCM is not good. Out of curiosity, do you know how much it'd cost to have the dealer fix the issue with the wiring and BCM? For me that'd be the determining factor. If 1,000 or less I'd be tempted to just fix it. If more than that I'd be tempted to trade her in and move on with life.

Looks like you can get a new AC Delco BCM pre programmed for $250 shipped on ebay. http://www.ebay.com/itm/NEW-VIN-PRO...7|Model:Avalanche&hash=item2339213956&vxp=mtr

Clip the wire closest to the bcm. It probably is short to ground somewhere. I doubt it fried your bcm it would show on other things if it did. Test your trailer reverse plug wire. If it's good use that.

that sounds like a good idea, if possible

 

[Neil Layne]

if you have to trade her in just take off all your stuff and put it on the new one and then that way we could be some of the few lifted tahoe/yukons in town. haha. I'm sorry you are having this many problems though, i hope there is something good out of this.

Shorts cause vehicle fires



Felix?

Hahahahahhaa just kidding

Haha I get it but a data wire can short and be fire free. I had that happen with my original aftermarket double DIN install.

 

[Goodinblack]

I honestly hate body shops even more than service shops.

Especially when they pull interior panels. The Bastards beat the panels back on and create rattles that were not there before.

 

[Bruizza]

Just read this entire thread. You have 2 sweet ass rides! Sorry to hear about all the issues with your Avy currently.

 

[08grey]

The backup lamp request signal is sent from the PCM to the BCM on the GMLAN serial data system. This signal is based on the park neutral position (PNP) switch signal. The BCM supplies voltage to the backup relay and to the automatic day/night mirror when the vehicle is in reverse. The backup relay supplies a voltage on the backup lamp supply voltage circuit to the backup lamps and trailer backup circuit. The engine may need to be running for the backup lamps to function.
Cargo Lamps

The cargo lamp is controlled by the courtesy lamp supply voltage circuit. When the dimmer switch is turned clockwise to the farthest setting, the BCM receives an input from the dimmer switch for courtesy lamps and cargo lamp to be commanded ON.
