    Tractor tail lights -- hazards ok but right one is sometimes slightly slower. Lturn wks correctly and right is on steady. Rturn wks correctly and left is not on at all.

    Side cab mrkrs were wkng perfectly then just stopped. Both wk for turn and hazards.

    Replaced turn signal switch (it needed it). -- same issues.

    THOROUGLY CONFUSED. HELP NEEDED.
