I've searched the forum up and down and can't seem to find anyone that has the same problem as me.

It started with the high-mount 3rd brake light being inconsistent. It would turn on sometimes and sometimes it wouldn't, then the navi started acting up saying one of the doors were ajar every time I would come to a stop or hit a slight bump. Now the interior lights won't come on when the key is pulled out, only when you open the doors and the rear defroster stopped working.

I've checked all the fuses and the connection for the 3rd brake light (underneath the trunk carpeting) and everything seems in order.

Could it need a battery replacement? Or do I have a short? I'm stumped. Thanks in advance!

 

have you unhooked the battery overnight to reset the bcm?

 

Haven't yet. I'll do that tonight. Thanks!!

 

Check the door sensors, make sure the rubber that covers the switch is straight.
