I had some electrical gremlins start up this past winter. First issue was the rear wiper running of its own accord. This happened in a snow storm, and has continued any time there is precipitation.
Friday night on the way home from work, heavy rain, I had the taillight, brake light, and turn signal light fuses blow at the same time. All three were replaced and did not blow. Yesterday the turn signal fuse blew again, but it was undersized (5a rather than 7.5a).
While off-roading a year or so ago, I had a log pop up and jam itself over the rear axle into the rear ledge of the body. That took out a ABS sensor wire, and the backup camera wiring the PO had added. This morning I started my investigation at that spot, but I do not see any other wire damage.
So I pulled both rear interior covers. On the driver side I found a loose bare wire, which I tracked down to a ground added by the PO. He had an affinity for scotch lock splices
. That wire has been removed.
The passenger side was full of mud. I've got a rust hole that was letting in more junk than I realized. Anyway, trailer wiring had been added by the PO, again using scotch lock splices. I plan on properly splicing and heating shrinking the connections ASAP. Clean all the mud out with a hose and pulled the wiring harness out of the quarter panel.
Question one is this connector. Un-used, but corroded to hell. Can someone tell me what it is for? Corrosion doesn't usually conduct, but since my issues only seem to occur when it is wet, and water and mud were getting into the quarter due to the rust hole, I'm wondering if the wet corrosion is conducting enough to cause the issues I am having.
Second question, does the rear wiper have a discrete ground wire, or does it ground through whatever holds it in place?
