Easiest thing is to check all of your fuses. If the fuse blows for self cancelling turn signals or flashers it won't recognize that the wheel is being turned. If all your fuses are good its possible the switch under the column is bad.

Edit: 335 may have an inline flow switch instead of the column mounted override switch. I've replaced a few of those. If I remember right its under the steering valve under the hood.
