Earlier I had mentioned my signal light randomly shorting, and you guys said it was probably my ground wire (or something to that effect). I was instructed to get it fixed by my mechanic, as it shouldn't take too long. Well, I'm going to get that fixed with my next oil change, so...
Anyway, My fog light went out again (driver's side, same as the shorty signal). If any of you recall, this was ~ 2 months ago.
My question: Could my recurring fog lamp destruction and randomly shorting (because it doesn't work, then comes back on again sometimes) signal (both driver's side) have a common source problem/solution?

UPDATE: It turns out that the previous owner of the car, upon cloiser inspection of the wiring to the fog lamp, swapped my power and ground to the fog light. I have fixed the problem, cleaned the connectors (Which was causing power loss to the bulb when load was placed on the wire), and the fog lamp works - now better than the passenger side.
The left turn signal apparently was a loose filament? I've never heard of this before, maybe because I'm such a car newB. But Apparently the bulb's filament was broken; but not so much as to cause a short signal, so much as to every once in a while turn off and on. Huh. Bulb replaced, problem fixed. At least it wasn't a wiring issue.
