I have the 460 engine. Runs good, but turn signal on left rear does not work. Elect window on left sometimes works. Both went out at same time. There are some wires under rear bumper that appear to be not connected. Perhaps someone cut them. Could this cause the problem? What else could be causing this? Thanks.

Soemtimes works, sometimes dont? If that is so I woudlnt suspect cut wires for doing that.

With the turn signal does the front one work? If so then the switch is good and you will have to check the bulb in the rear left turn signal and the socket for corrosion or damage. From there trace the wires up and see if they are damaged. If the wires were cut chances are the brakes wouldnt work either.

Yes, I agree. The front signal works but I went ahead and replaced the flasher and the taillight bulb. No luck. I shall test the socket and follow the wire.
