New BCM old problems...
So, for the past month Ive been having weird electrical issues with my 06 MCS like the brake lights staying on after I park the car, dash lights dimming randomly, blinkers occasionally working, both airbag lights are on and the seat belt light is always coming on and dinging at me... I did my research here and determined it might be the body control module acting up so I took it to my local mini shop to have it scanned to figure out whats wrong. Turns out it was a bad BCM so I had it replaced and reprogrammed today. When I picked up my keys after work they told me they had trouble communicating with the car but eventually got it to work, also that I have additional electrical problems. On my way home every single electrical problem I listed was still present!! The shop is going to try and track down whats wrong later this week but I am so confused as to what could be wrong, I thought the new BCM would fix all my faults. What could be the problem?
Thanks everyone!

Wonder if you have a issue in the wiring....causing the bcm to fail?
Some folks added an extra brake lights to tge back by jumpering a wire to an unused socket, and adding a bulb....many of these folks had bcm issues after a few years....
Assuming the voltage is good, and grounds were all checked pre bcm replacement too....
Part should have a warrenty.....i hope...maybe it was just bad? Good luck.
