I had the same problem today. Pulled the Trail/Rear Fog fuse and the problem went away.
Plugged the fuse back in and the problem did not come right back.
BUT, my remote unlock/lock buttons were not functioning well - very intermittent response to presses of the buttons.
Pulled the fuse again and the remote worked great.
WIERD!
Thoughts on a permanent fix?
Will my trailer hitch wiring no longer work if I leave the fuse out?
