Troubleshooting Trailer Park Lights Not Working on 2006 Ford Explorer

Updated 07/06/2020 | Published 07/02/2020

Question:

Where is the trailer lights relay located? All functions except trailer lights are powered at the hitch connector. My vehicle has the factory tow package, the fuses are good, wires and connections are good, but there is a relay that must be checked. I think it is in the rear compartment somewhere. Please help.

There is not a relay for the trailer parking lights according to your owners manual.. Relay 3 is for the park lights of your vehicle (but not trailer park lights) and fuse #25 is a parking light and trailer brake fuse with 15A that is located under your dash to the left of the steering wheel. If that fuse is good, then you have a short somewhere before your trailer connector. I recommend using a circuit tester like # PTW2993 to test the wire as you trace it for power to find the short.
