I bought an 03 cavalier with a Pioneer head unit already installed a few months ago. When I open the driver's door the radio doesn't shut off anymore like it should. Sometimes I can push the door jamb in and release it then the radio will turn off, but other times I have to pull the fuse out. I pulled the kick panel out and can see the wires running to the jamb and door, but I'm not sure what to do from there. Any help will be greatly appreciated.

Thanks
