I have noticed that occasionally my blinkers will start going fast or just stop blinking completely. All bulbs are good so I am thinking it must be the combo switch itself or possibly a ground. Has anybody been down this road?

 

Are they LED bulbs?
It could be the relay going bad or loose in the socket. They are located under the steering wheel. One relay for each turn signal so two total.

 

You were spot on. It was the relay. Thanks
