About two months ago, the heavy duty blinker relay on my Ranger
stopped working (blinker stayed lit), and I assumed that it was worn
out, since I had it in there for quite some time.
I replaced the blinker with the one the truck came with, a standard
relay, and it lasted a week before it decided to stop working as well.
Figuring it was also old, I replaced it with heavy duty blinker I had
from another truck. This one committed suicide in only two days.
Being frustrated, I decided to go purchase a new blinker. This time,
I picked up an electronic version, paying the extra money for it.
That was one month ago.
Tonight, this one has now died! The lights stay on when activated,
and the blinker makes a buzzing sound.
I have never blown a fuse on this circuit. The only aftermarket stuff
I have on the circuit are:
1) When I intalled a Class III hitch, a logic circuit was installed
under the bed for the trailer lights.
2) About five years ago, the above mentioned circuit was fried due to
a short circuit in a trailer. I remedied the situation by installing
a new logic circuit, this one going inline with a factory connector
under the bed. The old one has been left untouched.
Both of these have been in the truck up until today. I recently
removed the second logic circuit to see if it was the culprit, but the
blinker still won't blink, so I don't know if it is broken, or if the
problem still exists.
Any thoughts on what would need to happen to cause a blinker to fail
like this? I am kind of at a loss, given the problem's intermittent
Thanks in advance,
