Did I Blow Up My BCM or Something Else?
I was installing my switchbacks when something bad happened. I had one side 'test rigged' the way it should work, hooked the battery back up, then turned on the headlight switch to the running lights position. My diode exploded and I turned it off/unplugged the battery again. I discovered I hadn't put the turn signal bulb in upside down like you are supposed to for this mod - I had it in right-side up. At this point, none of the front (194), side marker, or tail lights would come on. Figuring it must be a fuse, I checked all of the lighting-related ones and they are all fine. I then checked ALL of the fused in both fuseboxes and every fuse is fine. Here is what is happening with no mods in place, everything like factory:
Turn headlight switch to running light position: The relay clicks like normal and turns off after 30 seconds like normal. The dashboard lights come on like normal. NO exterior lights come on at all.
Turn headlight switch to low beam position: Same thing, except low beams come on.
Turn high beams on: Same thing, except high beams come on.
The hazards work just fine front and rear.
The reverse lights work just fine.
Does anyone have any ideas? I also checked the ground wires under the left front headlight and they are fine. Where is the BCM? I'd like to take it out, open it up, and make sure I didn't blow a trace off the PCB. Thanks for any ideas...
