Hello! Welcome to justanswer!


You need to get the entire dash out. The core comes out the top of the case. See the pic below:

When taking the top of the dash out is there anything concerning the airbag I need to watch out for? Do I Just unplug the airbag?
Expert:  Anthony replied 7 years ago.
Sorry for the delay. Just make sure you unhook the battery before you take the air bag out.
