Turn Signal Won't Engage

I have a 1994 Oldsmobile Regency Elite. The right-hand turn signal will not engage. Left turn works fine. I've replaced the turn signal switch inside the steering column, however the problem continues to exist.

I'm now thinking the Multifunction Switch needs to be replaced. Any other ideas or instructions to remove the MF switch is appreciated.

Upon further inspection, it seems the wishbone-shaped bracket that secures the multi-function switch to the turn signal switch is the culprit. This bracket has a small post that is designed to slide inside a groove on the multi-function(windshield washer) switch. It pops out when moving the turn signal lever in the right turn position.
