Turn signal/Flasher problem

[hmmmmr]

I've been reading this forum for a couple of years and finally have a problem I can't find any previous answers to.

I have a 2003 H2 with about 65k miles on it. At random, when I try to use the left turn signal, the flashers will activate. Usually, all I have to do is cancel it and try again, most of the time that works. However, lately it sometimes takes 2 or 3 times.

Any suggestions?
