I have recently purchased a 2004 Ram 1500 Regular cab 4.7 4x4. It had a sporadic lamp out warning and no fog lights or low beam on the drivers side. I replaced the bulb and used some dielectric grease and the low beam works and the lamp out went away. I finally figured out the relay had been removed from the fog lights. So I bought a relay from Rockauto, put it in and the no low beam drivers side and lamp out came back immediately and still no fog lights. Removed the relay and lamp out went away and the low beam came back. I am puzzled. Any help would be appreciated!
