The rear is a NO
Additionally, when the turn sig is pressed, the front signal brightens significantly but does not flash. The rear right hand signal does not illuminate at all.

Pull the rear bulb, test for voltage by touching the positive voltmeter probe to the contact in the socket, touch the negative voltmeter probe to the frame or negative post on the battery (from this test we will know whether the issue is on the ground side or the positive side of the circuit).

If it is just a bad ground...
You should see system voltage, going on and off like the turn signal should.
If the issue is on the positive side, you will see no voltage.
