Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Do the brake light and signals work still? How about the license plate lights? Thanks.
Check fuse 8 of the Smart Junction Box (SJB) for a potential issue of not making solid contact in the fuse holder. If fuse 8 appears to show a good fit to the holder, inspect the Brown/White (BN/WH) wire's female terminal at pin 22 of the C2280e connector of the SJB to verify that the terminal and pin on the SJB are making solid mating contact. If the terminal of the connector also appears to be ok, run a replacement circuit from pin 22 of the C2280e connector to one of the rear tail/parking light socket assemblies to bypass a suspect wire issue in the harness. I'd also consider replacing the bulbs if you haven't already. Let me know how it goes or if you have more questions. Thanks.
The smart junction Box is what controls the lights. So problem is either SJB, wiring, or bulbs. Let me know if you have more questions, thanks.
