Brake light/blinker trouble

Going for a safety inspection soon, and ran into a snag with brake light/blinker:
 
Driver's side parking lamp does work, but it does not get brighter when brake pedal is applies as the passenger side does. It also does no blink with the hazard light does, and it does not blink when turn signal is initiated. Bulbs are fine.....passenger side is completely unaffected. The only other clue I can provide is that the turn signal up front on driver's side blinks much faster than the passenger side.
 
Anyone know what this could be? Checked all the other lights and indicators.....no problems. Again, passenger side works fine, and the light does work when parking lights are enagaed.....just the turn signal, and brake functions don't seem to work properly.
 
Thanks!
