    Running lights not working

    First off I want to thank everyone for the good information i have retrieved so far.

    I have searched through the forum and I had a few questions. Currently my 2001 passat has no running lights.

    Don't work:
    Tail lights
    license plate lights
    front marker lights

    Work:
    head lights hi/low
    blinkers/side markers
    break lights

    Using the forum I understand that it could be a fuse but which one?

    also relay 173 or it could be the headlight switch.

    I have checked all the fuses and they all seem ok. Above relay 173 there was a 20 amp fuse(hidden) that was blown what is this to? pulled out the relay and put it back in. Do relays go bad often? or am i better off looking that the headlight switch? lastly if it is the head light switch that is bad should i still get voltage to the fuse(which ever one it is) or will there be no power cuz the switch is no good.


    Thanks for the help
    sorry for the long post

    Yes, Thank you I was doing some more playing around and noticed that my DRL low beams still worked when i pulled the e-break. I found a simple diagram for the relay and saw what was going on.

    Is there anything else I should check before i buy a new switch?

    one person told me that if my dash lights still work that it isn't the switch. are the dash lights and the tail lights, plate lights on the same pins?

    No Running Lights SOLUTION

    I own a 2004 Passat, and encountered the same problem as "barnjeff".

    Bottom line:Running lights/Parking lights (noticed these terms are used interchangeably), went out in front, back, as well as the lights over the license plate. The solution was to buy a new switch.

    The switch was $40 at autopartswarehouse.com and it was received in less than 48 hours!

    Add'l info: Before buying the switch, I tried to troubleshoot myself. I checked all of the fuses; all were good. I checked the connector behind the light switch; good. I even whipped-out the multimeter and some other electrical gadgets to ensure current was flowing where need be to all the fuses, and even punctured the insulation of the wire which controls the running lights (GREEN with RED tracing). All were in good working order, thus it had to be the switch. So, crossed my fingers in hopes that it was the answer and it was.

    Good luck, folks!

    Katy, which switch did you replace? I have the same problem. Do you have a link?

    Thanks!
