Okay, so i replaced the turn signal switch and now my hazards, window wipers, high beams, brake lights all work, but no turn signals. ugh

I checked the fuse the have 12v, and I replaced the turn signal flasher. it is a 3 blade relay (I even used a 4 blade). the back of the relay I get 12v power to the pink wire.. I assume black is ground and the other purple wire not sure where that goes to.
Any help there? could the relay be bad?

any way of testing the relay? it say ebl (earth, ground and load, correct?)

where is the ground? to the turn signal relay located?

also noticed this green wire that leads into the turn signal switch cluster.. do not think it supposed to be like that or is it?

Hi and welcome back.

Do your hazard flashers work?

There is no turn relay shown in the diagram. Only a stop relay.

Below you will find your wiring diagrams. You should have 12v on the pink at the flasher. And make sure your flasher ground is good. If all your other lights work (including the brake lights) then your ground at the socket should be fine.

So I would follow the diagram down the line and check for voltage at each connection until you lose voltage.

Let me know what you find out.
