Check both sides of the FOG LPS fuse.

Is there power both sides?

If yes, is there power on the fog relay light blue wire?

It does not matter what position any switches are for the above measurements.

If yes, to power on the fog relay light blue wire, turn the headlights on.

Probe the brown wire of the relay.

Is there power there?

If yes, probe the yellow wire at the relay.

Is there power there?

The relay is located on the left inner fender in front of the brake booster.

In addition, make sure the headlights are NOT in the Hi-Beam position.
