Make and model? Where is the F/R switch? At your knee or on the dash? Most directional problems are caused by bad contacts in the f/r switch.
with switch on dash, I would replace the switch before going any further. The direction change is made at the controller, so if the f/r switch does not help, next would be to replace the controller!
