This is an old thread, but just wanted to pass on some information with this very problem. I swapped out steering columns as stated above my right turn signal would come on with the brake pedal being pushed. What I found was that my turn signal switch was tightened down very tight to the point that the plastic turn signal was slightly warped. I didn’t notice until I started troubleshooting this issue. Long story short, I had to back out each bolt until I found the one that was tightened too far down causing the grounding issue. This solved my problem.

Thank you all for this site, it is a life saver!
