Ever since I bought the D, the running lights for the trailer haven't worked, but all the lights on the D work. I have the factory installed harness that comes back from the underhood fuse blocks. Here's what I have checked so far with no failures:
-20A fuse, outside of the blocks underhood
-every fuse underhood has been tested with a light on both sides of the fuse
-all fuses are there that should be
-kickpanel fuses
I have no power coming through the pin designated for the running lights on the 7pin connector. There is a relay tucked under the rear bumper by the left taillamp that is wrapped in black cloth tape. I unhooked it thinking it may be the culprit, called my local dealer and asked about the relay with no luck- they said they would have to sell me the whole wiring harness. I took the relay out, brought it to Robbins Auto Parts and tried to match it up / look it up. They found one that appeared to be similar, but told me the relay wouldn't cause this issue and assured me it's a bad wire somewhere. I looked at the wiring in a few points and it is all wrapped in the black tubing and some points are wrapped in black cloth tape also- everything APPEARS fine.
What wire would I probe to check for power prior to this relay?
Any other ideas? I need to tow a trailer this weekend and it will be dark coming home.
Thanks in advance.:worthy:
