Took out my rear view mirror light bulb and it sparked a little when coming out. Now my door locks won't work unless car is on or I manually unlock it, interior lights don't work at all, and my stereo CD deck won't turn on either. Tried using my sunroof last night to find out that isn't working either. I checked my fuses inside the car and under the hood and replaced ones that were blown. Still nothing seems to be working. What else could it be? BCM or Relay? Don't know how to tell if the relays are bad or not.

Hi,

The easiest thing to do to check a relay is to switch it with a different one in the box having the same part number. If there isn't one, here is a link showing how one is checked:

Based on the schematics and what doesn't work, I have a feeling fuse 5 in the junction box/fuse box at the end of the dash is bad. Do me a favor. I need you to recheck that fuse. Additionally, I need you to confirm there is power to it. Here is a link showing how it's done:

I hope this helps. Let me know if you have other questions and what you find.

Take care,

Joe
