Turn signal failure
1993 XLT Ranger. Replaced the ICM a few weeks ago and right after the turn signals acted up for about 5 min. Didnt do it again, forgot about it till now. Taped into the purple / orange wire for 12v power for a tach and it started acting up again. Pulling the tach wire off of the turn signal circuit didnt help. Replaced the round flasher in the fuse box under the dash, didnt help. The wiring diagram shows another flasher but it is not be found anywhere.
Symptoms;
-Both dash lights come on and blink when either turn signal is on.
-Both front turn signals always come on, regardless of witch side is triggered.
-Both dash lights come on and stay on with the head lights ( but will blink when triggered )
-After on for awile they will slow down.
-After a long drive they will not come on at all.
Thanks
