4 ways all work fine but right front signal deosnt come on when right signal is used and light in dash only blinks on right side when 4 ways are on

Not sure I fully understand please be more direct in question please but it may be a turn signal switch.

The signal indicator light in the dash and the front bulb but the rear works when regular signals but all lights work in hazard

Sry meant to say dash indicator and front signal only work.when hazards are on. When using signals only right rear signal comes on

Thanks i will try the grounds and the bulb sockets but the bulb in dash and bulb on right front signal flashes when on 4ways but not when right signal is used, the bulb is a 3157 which has two terminals one is for marker lamp and one is for both 4 ways and signal is this right and if so then the wire socket fuses and bulbs all work just have issue with signal function
