OK this has been an ongoing question as far as I see. Are you 100% sure this is the right column. There were some changes. Compare the plugs. wiring should be identical colors and positions - if not I think we found the problem. You had one wire pinched already ... check the harnass (this requires dis-assembly or probing each wire for continuity), make sure the tilt hasn't broken a wire or two and make sure you re-use the factory wiring shield. The turn signal switches are cheap but tearing into the column to replace it can be a chore ... believe I just went through it. I wanted to replace my column instead of fixing it but could not locate the right one anywhere (then again my 81's column {floor shift, wipers on dash, tilt, cruise} is a tad less common than an 86 model's).
I don't want to sound like a dick but know exactly what the donor was would help.
