headlight problem :(

[LANCER_5]

My passenger side headlights are alot dimmer compaired to the driver's side. I've changed the bulbs and still the same problem. and when I turn on the highbeams the passenger side lights are completely off... kind of seems like i dont have enough power.
i've checked the fuses and they look fine. any idea what i can do or what else i should check out?


thx

Check for shorts in the wires leading to that light. Also easy way to see if enough power is getting to them, just get a voltage tester and test it that way.

be sure to check all the grounds too.

This sounds like exactly the same problem I am having. In my case, the problem is due to an intermittent electrical connection between the headlamp connector and the wire harness that provides power to the headlamp. The connector is barely visible in the small gap between the bottom of the headlamp and the front bumper. There is just enough room for me to slide two screwdrivers into this space and use them to push the two connectors together. When I do this, the headlamp will return to full brightness and remain at full brightness as long as the lights are left on. To properly fix this problem, I will probably need to remove the front bumper and repair/replace the connector or clean the terminals - I've just been putting this off for too long.

The plugs are probably shot. Replace with parts off the rack at Autoetcboys.
The plastic in the factory lamp plugs is too brittle, and the spring strength in the sockets isn't strong enough.
