OK I've been on here looking for answers on headlight leveling system, Currently my lights are pointing down when I get in the car my Beam focus is about 2' in front of the car. So I got a new rear headlight sensor replaced it and the lights are still in the same position... So I read that there is a front sensor, What does this sensor do is it for left and right or up-and-down... The big question I have is how do you read move the sensor at the plugin part... I see this to bolts That hold it in place . I cannot disconnect the from the housing it A pain in the ***. Judging from the pictures from people who are trying to sell I it was difficult for them to remove so they just clip the wires. Is there a way or technique to Unplug it from the female side.
