Hey guys. New here. I had a Body shop weld a huge part (from another 2014 Jetta Wagon) from the driver fender to the back driver door due to an accident.
Now the ignition won’t even come on. Only basic things like headlights, radio, unlock/lock button, and the dashboard showing the mileage works.
After digging a little, the welder got really close to the Body Control Module. There’s even burn marks on it and one of the relays looks burnt. The relay isn’t bad though and when I unplug the BCM, the car has even less functionality.
I read that if a BCM is bad, it affects power mirrors, power windows, air conditioning, and the immobilizer system which all don’t work.
I’m guessing it is the BCM, but can it be something different like the Ignition control module or ECM? It also has the power steering issue light on the dash.
I would really appreciate some info on this. Thank you!
