Toyota Repair: turn signal flasher?, left turn signal, tacoma 4x4

Question
hey there, I have a 1996 tacoma 4x4 and I love it!  I have a slight problem however.  About 3 months ago I noticed that my left turn signal was flashing faster than normal, so with the knowledge I posess, I replaced practically every buld I could find in the tail lights, signals and brake lights, front and rear.  Its still doing it and now when I touch the brakes the left turn sticks.  It has a weird schedule for when it works and does not work and it seems that recently its been geting worse.  I think it might be the flasher and I bought one but I cant figure out where it goes, I have looked everywhere!

Answer
Flashers rarely ever go bad, in all of the 27 yrs I have worked on toyotas I can't recall ever replacing a flasher, I have seen lots of problems caused by trailer hitch wiring, does it have a towing hitch and if so I would suggest disconnecting the electrical connections to the hitch to see if the problem goes away.
