turn signal flash really slow ...

The 67 barracuda saga continues, checked everything discussed on the post, thanks for the insight. However, I sent the day chasing down my issue. I thought its was a bad socket sooooo...i drill it out and replaced it with the dormen..thats was a job, but came out great...STILL DONT WORK RIGHT. When i ground the light it would be really bright but the turn sig. still wont work, remove the ground and the turn sig. works really slow.......i did some more research, could it be the turn signal switch in the column?
