My Defender is a 1992 model 110. Of course the hazard and blinkers don't work. I've replaced the relay, the hazard switch and confirmed all my fuses. I've confirmed no shorts or poor connections. When I engage the blinkers, the dashboard shows a steady light. Both blinker lights will light one at time if I push/pull the blinker lever manually. Everything seems to be in place for the hazard and blinkers to work, but they don't. Could it be a bad blinker bulb (even though both lights seem to work)? Would anyone like to take a whack at diagnosing the problem? I'd be very appreciative . I don't know what else to check. many thanks.
