Drivers side light problem

[rroryboii]

I used to get the old "disco light effect on the back lights when I indicate and brake it goes mad but I fixed this and now my drivers side tail gate and drivers side side light does not work at all I keep getting pulled for it plus MOT is soon , iv checked fuses and earths , changed bulbs only thing I can think of is test the circuit anyone got any idea's or had this before?

Maybe check the connectors for the lights?

I have , I stripped my whole boot today to check everything the connector seems fine but I forgot to test it -.-

Hmm the only thing i could think would be the whole bulb holder? Strange that front and rear would go at once

Nah I tried that still doesn't work, it's winding me up . It's all been happening since I tried using my electric mirrors blew a load of fuses but it's all been changed

Usually disco lights in a rear cluster is the sign of a bad earth, have you checked the earth points?
