I am having similar problems. My front right headlight was not working, brand new bulb, good connection. So I took it out and tapped it really hard, and gradually it lit up, and stayed lit. After having to do this several times at night, it now works all of the time. The main problem for me is the lights on the back right side of the car. I have replaced them time and time again, and they seem to go out every few weeks. I am beginning to think it is a bigger problem, but don't know where to start. I have heard that a battery running too rich can be a problem. Also, my dashboard lights are all out, including the AC/HEAT knobs and anything else that would light up inside the car. Although the warning lights still work on the dash. So basically the only light I have inside my car is the light telling me my lights are broken, just a little irony right there, but if anyone has suggestions other than the relays. Fuses maybe? Thanks.
