The left turn, brake and four way/hazard signal do not work. Running light on left side still works. Have replaced bulb, checked all fuses under the hood and they check good with a meter. Disconnected and cleaned battery cables and terminals and coated with Vaseline. Still does not work. All other lights in the front and right side of vehicle work. The left backup light still works. Where do we go next? Thank you for any help you can give.

Remove the tail lamp housing and using a test light connected to a good ground. Probe the White wire with dark green tracer, with the hazard lights on. Probe at the pigtail connector from the body first. If you have a flashing test light while connected to that point check the connector for corrosion. If it looks good check the same wire right at the connector for the bulb. If it is out there you need to replace the pigtail and sockets for the light.

for this test method

If you have no power in that wire at the connector then you need to get to the body control module and probe that same wire at terminal two in Connector two. If you now find power, one of the two connectors in that wire have corroded. The easiest repair for that would be to run a bypass wire. If you have a trailer tow package there is an additional connection to that harness as well.
