Some older controllers have an adjustment on them to "level" the sensor on the controller.....check that. Also, put a test light on the brake pin at the connector and manually operate the controller...the light should go from off to bright as you slide the switch on the controller.
Do Brake Controllers Gradually Go Bad?
