Disconnecting A BMW Battery CAN DESTROY THIS EXPENSIVE PART!⚠️

Here with this car. These are very, very common issue with these vehicles. It could happen randomly at any time. I'm assuming that somebody probably tried to jump start it. Do we know if the windows work when it came in? Yeah, because I rolled them up and down. You were able to roll those up and down? First time we pushed it in and then we pushed it back out and then I rolled them up and down. They worked. Okay. So any time this car gets, you know, jump started, could cause this problem. Battery disconnect. Just a normal old everyday battery disconnect and reconnect can cause this issue and it will cause windows not to work, turn signals not to work, all kind of lighting problems. And it all has to do with one module in this car. Now, what we're going to do today is fix this module. We're going to try to make this module work without buying a module for this car. And that module is the footwell module. So what we're going to do is we're going to remove the footwell module out of this car and then I'm gonna show you how we're gonna try to fix this one. While Eric is getting to that, let me kind of tell you what the footwell module is. If you think about it, it's kind of like a body control module in other vehicles. It controls a lot of the lighting, it controls a lot of the comfort systems in the vehicle. I mean, there's other models that are involved in that also. But this one is a very, very touchy module. I mean, I can't tell you, you know, back in the day before we figured out that there was a way to potentially fix these things. These got put in, you know, like potato chips. But once people figured out that the dealership probably doesn't do that, they don't go in and try to fix it. They just replace it. Sometimes you can go in and try to reprogram it, but most of the time from what I've seen, that doesn't work. You actually have to do what we're going to do here. And that requires a lot more work than just reprogramming it through the OBD connector. We're going to show you what that takes. There's going to be some disassembly.
