    Default Right turn signal issue

    Kind of a weird issue with turn signals.
    Drivers side works fine. Passenger side will light up solid but not blink in the rear. In the front drivers also blinks fine but nothing for the passenger front at all. Not even a solid light.
    Dash indicator blinks for left but goes solid for right.
    When hazards are on all but passenger front blink(no light at all.)

    Any help is appreciated.

    May be similar to probs i had. Listed repairs that fixed them.
    Main harness is sound. The first step.
    From my notes:

    8/22/2006
    rt ts inop ind, rt dash light stays on tl bright, lt ok flash ok
    Repair bad ground- replaced ft rt turn signal socket assy.

    5/28/2007
    no rt turn signal
    Replaced turn signal switch assy in steering column with 7.00 salvage yard part 1980 Merc Zeph.
    Sort of used the salvage switch as a test part. Worked fine, corrected problem left it in.

    no rt turn signal or brake light.
    Replaced turn signal switch. Brand new AZ Duralast combo switch.

    Slow ts flash ds
    Replaced ds rear 3 wire running light and incorrect 4 way flasher.

    Found most of the time, inop ts, brake, running lights are socket related. Age.
    Swapping good working bulb into inop circuit eliminates suspect bulb. Rarely do quality bulbs fail.

    Lighted 12v test probe and multi-meter help a lot.
    Console graphic LED display helps very much in diagnosis and confirming repairs.
    I buy the correct spare socket pigtails to keep in my parts inventory.
    Sometimes have to got to several stores to find the right ones.
    Little bit of bulb grease in socket is icing on the cake. Factory used it.
