Right rear turn signal bulb was constantly on one day with no key in ignition. Had to unplug harness to get light to go off. Plugged harness back, now have no turn signal. Test light picks up tail and stop but not turn. Signal flasher flashes as if bulb burned out (fast). Bulb is good, front and mirror signal works. Can hear the flasher operating. When cruise is on and r/turn is activated, cruise cancels. Could it possibly be a bad flasher?
Cadaver is exactly correct . Its a dead short
This guy nows exactly what he it talking about nothing I can add
The wire is shorted.
trailer hitch hack job.
collision damage to rear.? wrecked the harness.
why would the flasher be bad, if left side front and rear works perfectly
we use a 15amp circuit breaker to replace the flasher fuse.
then find the short, (beaker keeps popping) when right turns are selected.
is this car under warranty?
did some one put in an illegal larger fuse in this circuit? dont
its a simple shorted line
we have a thing (real edison like) called an ammeter
we can measure the actual short, all look here its 15amps
just as the breaker trips, bingo city
then all we do is start pulling all inline connectors to find the section that is shorted, front or rear.
does that help?:
Just Right turn signal not working in rear. Back light and brake light working.
Front turn signal works but blinks fast.
Checked fuses and bulbs.
ok RR dead,, off or stuck on, and RF is fast , that fast means there is s short. so why not replace all lamps on right side 1 by 1, (both) fixed now? (lamps do short) and if not fixed now that means th wiring is bad. there. on rear is my guesss, the one most dim is most shorted. see? most DIY just replace the cheap lamps. first. before going deeper, or swap left for right of (far afield, etc)
i have the 2010 book, and it has TURN module, with 4 outputs, i think they are isolated, front/rear but, if the rear is shorted, or lamp out , it flashes fast to tell you, its bad. see? why not replace RR bulb, (checking for collision damage there, and trailer wiring hacks)
keep in mind its a computer doing the blinking so can be programmed to blink fast for zero current and too much. as a warning to the driver, the video link is here, and both lamps in video are the type that love to short. (cheap brand lamps= do that easy.)
now you know where it is , and how to change it. the lamps have numbers on the side, (if lucky) if not lucky the operators manual in the glove box lists them.
