Drivers side rear lights.

[br0dy]

Here's the wiring diagram for your rear tail lights. I believe position light can mean either the front, rear, or side marker "turn signal" lights? I might be wrong on this.. whenver I have a bulb failure I turn on the 4-way hazards and walk around the car while my wife plays around with the shifter and brake pedal.

It seems your issue is isolated to RSH5 or RSH4 which are the shunts for the tail lights. Swap them and see if the issue follows the shunt? That's where I would start.. also check continuity of that green wiring feeding your tail light make sure you have continuity and notihng shorted to ground fault. Sorry I am learning myself so hopefully I am not giving you a bum steer.

Also just thought of something. Did you plug back in the interior ceiling light that had to be unplugged for the top trim? I seem to remember that causing an issue when I had mine apart.

Thanks for the diagram brOdy,unfortunately it might as well be in Martian as far as I'm concerned,I can't make head or tail of it. I'm following up on what Hoonk said about the system turning off.I'll report back any progress in tha direction.

Here is a portion of that Diagram. 10/18 and 10/17 are the left and right LOWER tail lamps. A green with white stripe wire (GR-W) on one side and a green (GR) wire on the other feed battery voltage to the rear parking lights. Note the jumper from terminal a:1 to terminal a:5 on the left side - appears to be a single bulb up top (the circle with the x in it) and a double filament bulb below (two small x's) - Meaning 2 parking bulbs on each side. Terminal a:6 on the left side has a black wire (SB) which is the ground wire, shared with the ground for the Licence plate lights (10/3) The ground wire terminates at 31/72 which is a bolt in the body - the location of which is listed in the back of the wiring diagram books. The areas that look like there should be wires going to them on the tail lamps actually do - the lower two points below a:1 and a:5 on the left tail lamp are for the rear fog lamp and the reverse lamp. Only the wiring pertinent to title of the diagram is shown. But the other two wires in the connector should be a blue wire for the reverse bulb and a pink wire for the rear fog bulb.

With the parking lights on you should find Battery voltage @ the GR-W wire and the GR wire. The REM (rear electronic module) determines when to send power to the parking lights via instruction over the CAN (controller area network) network from the CEM (central electronic module). Parking lights are fused left and right. In the larger diagram the fuses are called 11C/30 and 11C/31. All the left parking lights (1 in front and 2 in the rear) are on one fuse, the right 3 on the other. The right fuse (11C/31) appears to supply power to the license plate lamps also.

Fuses 11C/30 and 11C/31 are in the "C" fuse box, position 30 and 31. There are 5 fuse boxes in the car, the "C" fuse box is under the cover on the left end of the dashboard, visible/accessible with the door open, and there is a legend on the back of the cover.

But going back to your original post - you said you removed the UPPER tail lamp to replace bulbs - did you replace bulbs in the UPPER and now you have Parking light problems? The UPPER tail lamp has the brake and turn signal bulbs in it.
