With the wheel and adapter hub removed, you can now get to the turn-signal mechanism. Next, remove the column mounting bracket and wiring trough. Inspect the signal mechanism for broken plastic canceling tabs. Electrical checks should be made to ensure the switch is working (see sidebar). Unbolt the turn-signal arm first and then the three small retaining screws from the plastic mechanism. The switch wiring probably won't come out of the column at this point, but there will be enough slack to pull the switch up and swing it out of the way.
