yeh its the small plug is the indicators.
its just a common contact(power in) switching to left or right contact.
have a look for the green/blue wire contact thats the left indicators
green/yellow is the right.
now match up the pins to the switch,the one thats left is the common.

are u running higher power headlight bulbs than stock?
sounds like your prob is outside the switch & more up at the front left indicator...
