The left rear turn signal has stopped working. Bulb has been replaced and so has the socket. The tail light half/section of the bulb illuminates so socket is getting power. The front signal blinks rapidly as if the rear bulb is defective. The hazard blinker works on all locations except the left rear. Any help would be appreciated.

First you need to determine which you are missing at the socket. Power or ground. If it's ground it should be in the trunk area close to the light itself. If it's the power, it's somewhere between the lamp socket and the turnsignal switch. According to the diagram, the wiring color is the same from the light socket to the TS switch. You should be able to check output from the TS switch at the connector below the steering column. If you have flash at the connector, it's somewhere between there and the light. Hope this helps.

I have put a multimeter on the connections after changing the socket. The socket is getting ground as evidenced by the tail light half of the lamp working. I can find power on the lead for the tail light. I can find no power (I would assume the meter would pulse) of the turn signal side.

Apparently you have an open in the circuit from the dash connector to the light. As I mentioned earlier, check for a flash at the connector under the dash. If you find it there, work your way back until you hind the open. If you find the same color wire at the connector with no flash, check the switch. Just had a thought. Does the light in question work with the brake applied? Let me know.

No, the turn signal does not work when the brake is applied.
