    Right hand side headlight s not working no more even though the bulb s good and the lights on the dashboard are blinking time to time... I hear the relay making sounds,but since the dash light is fine and working properly when i turn the position lights on i went out to look for shortage somewhere around the headlight.
    Got any suggestions how to aproach on the issue?

    Tnx in advance

    Freightliner?
    Dash lights blinking?
    My Right headlight would pulse very intermittently also. like once in two minutes. with the switch off.
    Chassis module connections got wet; behind cab on frame.
    Try blowing it off with shop air, unplug and blow out each plug and socket.
    Mine went away completely on the recent 70 degree days.

    unhook the trailer power cord from the cab and check to see if same problem is there, Sometimes them cords go bad and with these computer controlled units it presents problems all over.
