Turn signals and hazards worked intermittently and now don't work at all.

Hello, The combination switch for the turn signals is the first thing I think to test. Yes, please test before replacing. The combination switch is the actual lever you use to activate the turn signals. Check to see if your horn works too, as the combination switch also houses the SIR coil (clock spring) that sits behind the steering wheel. The steering wheel must be removed to replace this assembly, and this is likely the issue. Removing an airbag will cause serious injury or death if done incorrectly.
