Troubleshooting radio/power windows/brake light
 

I have a 2004 (40 yr anniversary) convertible mustang 5 speed with a 3.9L V6
Two days ago I noticed that after down shifting and coming to a stop when I took off the ER brake light came on. And yesterday the radio wouldn't come on while the car was running but would come on when I kicked the keys to the back. By the time I got home last night it did not matter what potion the keys were in there was no radio. This morning still no radio and the power windows are not working anymore either. And when I stopped and went to take off the brake light started coming on again. I have looked into a few things and some are saying possible BCM issues. Any other ideas or suggestions?

Welcome to the forum. Sorry I can't help, but if you'd start a new thread in the appropriate Tech section, the specific to your year Mustang, you'll get more responses in there. Good luck

After a few clicks I see the different areas now. thank you!
