Flakey Turn Signal

[etmyers]

Need some help...

I have an 06 H2 with a flakey left turn signal, right side works fine. Sometimes the left works. Sometimes the indicator will light up on the dash but does not flash and the turn signal lights all light up with the exception of the side marker light. When its working the side marker flashes like normal.

I have taken it to the garage, of course it works there and doesn't act up at all. They told me that unless its totally broke they can't determine if its the switch on the steering column or the module on the back of the fuse panel on the drivers side. If they replaced both it would be $300 plus labor, $100 for the module and $200 for the switch.

Anyone have similar issue or how to isolate it without replacing both? Suggestions on where to pick up parts other than the Hummer dealer?


Thanks a ton in advance
