I can’t seem to figure out why any of my marker lights will work. I have rear driver side brake lights on the bottom nothing on top nothing on passenger no power going to the harness at all for the right side. Can’t seem to find where to order another and when following the harness I loose it so does anyone have any diagrams also I checked fuses under hood under wardrobe and under dash on driver side none are marked so also need diagrams for that Google is not much help

Sounds like a grounding issue. I found that the top front marker lights aren’t sealed very well. Water leaks in at the wells in the fiberglass at the marker lights. This happens more when driving in a rain storm, water is forced in.

Rear tail/turn/stop light fuses in RELAY/FUSE CENTER, under hood forward of driver, near radiator.= 1-2 of the SMALL RED (10a?);

IF YOU TOW, Inspect/ repair rear tow harness BEFORE REPLACING ANY FUSES. Otherwise, check bulbs/ sockets? Good Luck. (FYI/TIP: FRONT Turn Signal/Parking lights in fuse panel under dash)
