If it's intermittent and front and rear do it at the same time, i would suspect a wiring issue such as a loose ground wire. If it's only front or rear when it does it i would suspect an issue in the clip connections for said signal
With a new multi function switch already, I'd look to the flasher. I've had my own flasher go out on my TB. It's located on drivers side behind the knee panel. Drop this panel down, about 3 or 4 screws up on top. The flasher is normally located attached to the back of this knee panel, but have seen it swinging loose back there too. It's a big flasher, about 3" long, and 1.5" wide. Suggest replacing it with Novita LM486, which works with both incandescent bulbts and LED bulbs. Novita makes the flashers for GM.

After driving today, I parked in my driveway. The right turn signal would not work and the emergency flasher did not work on the right side, either front or rear lights. I turned the steering wheel a quarter turn and the right side worked for both turn and emergency flasher front and rear. Does that make sense?

FJ4072 was right on the money. I replaced the flasher with the OEM model and fixed the problem. Thanks.
