hello everybody
i just bought 03 ml500 with xenon headlights (without projectors). i think these lights were an upgrade in previous models. now when i start my car. all rear front lights including high beam turns on. if i turn my switch to auto, park or off. nothing happens. when i push it for hight beam, no effect either except i get high beam sign in my dash which is normal. but no control over lights. what could be the problem. thanks in advance for your help
