    Hello,

    I am writing to see if anybody can assist me in diagnosing my issue. When I turn on my fog light it blows my fuse of the right headlight.

    Thanks for all the help if possible.

    I have never heard of a car with fuses for headlights. They usually use a thermal breaker. What rating is this fuse, and where is it located?

    The fuse is a 15 amp and it is in the fuse box on the side of the dash on the driver side.

    There are a total of 4 fuses in the interior fusebox. Left/Hi beam, Right/high beam, Left/low beam and Right/low beam.
    Fuses # 11, 12, 15 and 16 shown on p. 8W-12 here:

    Fog lamps only work on low beams, so it is fuse # 16 that blows?
    Fog lamp circuits are shown on p. 8W-108 (LH 63). There are slight wiring differences between DRL and non-DRL cars.
    The right h/lamp and right f/lamp share a ground.
    The short may be in the headlamp switch or possibly in the wiring to the front of the car. The switch wiring is shown on p. 8W-102 (LH 57).
    If the fuse blows right away or you can 'make' it blow, it should be fairly easy to find. It is only when fuses blow intermittently that they can be hard to find.
    Look for cut, pinched or rubbed-through wires. Look for burnt or melted plastic. Likely a Dk. Blue or Vt/Rd wire is involved with the short?
