I want a second opinion, or a third or forth, basically Iam opinion to you input.  I have an 03 Avalanche and have an intermitent problem. My left turn signal stops flashing occasionally when I put on my brakes.  The light stays illuminated but does not flash again till I let off the brake.  Only does it once in awhile but its becoming more frequent now.

I have replaced the bulbs, and the dealer has replaced the connection box under the rear fender.  Iam starting to think its the multi function switch.  My reasoning behind this is the four way flashers stop when the brake is applied so there has to be some connection there between the brake and the multi function switch.

What are your thoughts?

Thank you in advance
 
I'm thinking it's the flasher module
 
Thanks, ANOTHER part to consider.  I was hoping this wasnt going to be an easy fix and not a trial and error repair job.  The flasher module does seem to be the cheaper and easier fix to start with.
 
From what I have notice on the site 90 % of the time it is the flasher.
 
2003 1500 w/ 150K miles.  I am having the same issue.

Any idea which part is the "Flasher Module"

The four pin or the larger one?

I presume this is located under the dash?

TIA

There is also a thread on repairing the turn signal flasher module.
