Left Rear Turn Signal NOT Working

[RobertLang]

It is the left rear turn signal AND LEFT BRAKE LIGHTS that are NOT working.

Previously I said the brake lamp worked. It does NOT.

The Left Rear Turn Signal AND BRAKE LAMPS are NOT Working on my 2002 Jayco Granite Ridge. The running, and backup lights are fine and I replaced the bulbs just to be sure (and even tested the bulbs via putting them in the right side). In front of the Jayco, the left turn AMBER indicator flashes fast. Inside the cab, the turn signal indicator blinks faster than usual.

I tested for current with my meter and NO CURRENT flows to the back for the LEFT TURN SIGNAL (and I tested the right, just for grins and see how it should react).

If I put and extra bulb on the front AMBER bulb, inside the Jayco the turn indicator flashes normal.

Cannot fix with a new wire from the front to the rear via the same wire that sends current to the left front AMBER turn light. But I thought I ask . . .

ANY FUSIBLE LINK in that turn signal line? Anything else I should do before running a new line?

THANK YOU!!!

Most likely cause:
Corroded socket or wire connection behind socket.
Open ground AT the socket.

If that doesn't pan out, trace the flasher wire back as far as you can; you may find where it has been cut or pinched.

Look in chassis owner's manual for fuse locations. Some companies wire the coach lights through the trailer connector wiring harness. You are looking for trailer left turn fuse.
