Welcome back:
Is power at both ends of the fuse? I ask because often times a fuse may look good but be bad. Also, are the pins where the fuse mounts in good condition and not pushed in or corroded?
I have to be honest. I looked through the wiring schematics for you and I don't see how it could be related to a ground issue because of two reasons. First, they work with the hazard lights and the grounds for front and rear are in two different places. See pic 1
If you are certain that power is making its way through the fuse, the next check is the body control module and then the switch. If you look at pic 2 (sorry for the poor hand writing) it shows power in to the body control module (BCM) from the fuse I asked you to check. From there, power goes to the switch (See pic 3). The directional light selected then allows power to ground completing the circuit. So, if the switch ground was bad, the left wouldn't work either. Somewhere between fuse 11 and the switch power is lost.
What this requires is for you to locate the body control module under the dash and then check the pins in the attached pics for power.
Please let me know if that is something you can check for or if you have questions or need help.
Take care,
Joe
