I am having problems changing the rear left brake light from my 1994 850 wagon. I don't want to break anything in the process. Any help would be great. Also when changing the battery is there anything special that has to be done to change it or can I just remove the terminals and place another battery in.

 

Disconnect the negative terminal first.Then leave the key in the on position when installing the terminals.
Also make sure you have the radio code.

The lightbulb assembly should come out for you to replace the bulb.
