Automatic headlights

You got a good dealership! I talked to two about BCM programming, all I got was blank stares and un-returned phone calls.

That is because most dealership techs are computer operators who can change the parts on your vehicle only after the computer tells them which parts are bad. If you are not doing cookie cutter tech things they have no clue on how to do it. I had that issue with mine until I finally got the answers the tech needed for him to do the updates on my headlights. All he had to do was contact GM with my VIN number and request a re-flash program to turn the automatic headlights and daytime driving lights back on. (I also found out that they can NOT turn the speed governor off without a written letter from the Police Department on official letterhead requesting the change and they have to explain WHY they need it turned off so that GM is not liable if the Police Department has issues when the vehicle exceeds the 99MPH that the governor is factory set at on the SSV.) Then GM charges the dealership $50 for the re-flash and then sends the new program to the tech to install in your vehicle. It is an easy operation but getting someone to understand what you want and how they can help you is another story all together. LOL!

Yes but won't they will come preprogrammed for how the vehicle came from the factory? That would still not resolve the changes he is looking for without additional updating. At least that is my understanding but I could always be wrong.

getting another bcm programmed to vin make's it just like any other off the shelf tahoe, it would no longer have any ppv/ssv programming.
the vin is not ppv/ssv specific., the vin simply defines what parts the vehicle has and does not have, there are no specialized ppv/ssv electronics or engine parts that make it different than any other vehicle.

My point was if you program it to the VIN the VIN knows the vehicle is a PPV/SSV and would be programmed accordingly as the vehicle left the factory? Unless you got the VIN to a regular Tahoe and had it programmed to that VIN? Not 100% sure on this but that is what the tech told me just now.

$295, get the AutoSync, add/delete what you want and enjoy your one touch up/down d/s window and auto down for the rest, keep the rest of the PPV features. BTW it’ll also unlock a factory Navi or radio to slide in there.

no it doesn't work like that, it would just be regular programming
ppv/ssv programming is not even available to the public or 3rd party, although some places do custom programming that could emulate a ppv or anything you want.

Try a different dealership as I got it done so I know for a fact it cost $50 to get the program from GM to turn them back on.

Going to try the local GMC dealership by me. Can’t hurt to ask

Might be $400 (with BCM programming) to deal with the autolights.
