The connections at the light have been checked and found to be ok. With the turn signal turned to the left, both lights come on, but do not blink. With the turn signal turned to the right, both lights come on, but do not blink.
There is a black box behind the drivers seat, but it does not contain fuses. There is a sealed (white) box behind the passenger seat? When you refer to fuses under the dash r/f side, do you mean the passenger side? If so,
how do you get to it? There is a cover panel, however it does not have blind nuts on the inside and the nuts turn with the bolt.
