Electrical Issue C5
2001 C5 Corvette base model convertible
Ok, so I've been chasing and troubleshooting an electrical issue, originally thought it was MFS related, but not certain at this point anymore. Here are my findings
Turn on hazards -> turn signals flash along with fog lights opposite of each other.
Turn on hazards w/ taillights removed -> front markers flash as expected. no fog lights flashing
Turn signal on w/ taillights in -> fog lights flash opposite of turn signals
Turn signal on w/ taillights out -> rapid flash front signals (as expected w/o bulbs), no fogs flashing
press brake pedal with all bulbs installed -> car dings like key left in ignition
lock car w/ keyfob -> car alarm goes off
replaced the MFS, things worked for a couple hours (I think... may not have tested it correctly without knowing all the combinations what weren't working correctly)
EDIT: All stock bulbs in the taillights, not LED bulbs

Good question, no, replaced all bulbs with Silverstar bulbs again too, just to be sure there was nothing wrong with the old bulbs

Ever in a flood or anything, does it rain a lot where you are, car garage kept? Hopefully Bill Curlee or 8VETTE7 chime in they will point you in the right direction........
Could the BCM be his problem guys?

Was working fine one day, then next (or even later in the same day) it started acting up. Initially thought I had a blown signal. Until I'd push the brake and the signal would stay on solid on the dash (forgot about this writing initial post)
Where would I begin searching for the ground that affects the rear lights?
I'd hate to go and pick up another MFS at $150 a shot when it's unknown if that's truly the issue. I wish there was a way to better test those :-\

Have you read through this? This is one of Bill's threads as I said he and 8VETTE7 are the guys you need in this situation maybe DM them or something asking for help they are both very nice guys and very helpful.
