Only one turn signal working

Hey guys, I recently have been working on my new 1999 taco which is a pre-runner build and only one of the turn signals functions. I have replaced all the bulbs and housings and this hasn’t fixed the problem, i’m going to replace the flasher relay next which I doubt will solve anything because one of the signals still works. Thoughts?

 

Have you cleaned the leads?

 

check the wiring at where you put the bulb in. Salt will corrode it and break it apart. At least thats what happened with mine.

 

Do the emergency flasher lights work??

You have only one bulb working or one side??

You say you replaced the housings did you mean sockets they tend to corrode

 

This is an important question, if they both work.
The problem probably isn’t the flasher relay.

You say only one of the Turn Signals function?
Can you elaborate on which one?

One side (Right/Left)?
One bulb?
