I've got 12V at fuse #10 and foglight relay pin #30.
12V at fuse #10 is good. #10 also powers the horn.
What voltage do you read at foglight relay pin 85? Should be 12V. This voltage comes from the foglight switch.
Once 12V at pin 85 is verified, check foglight relay pin 86. Pin 86 should be 0V with headlights on and on low beams. Pin 86 is connected to fuse #1/#2 which power the high beams.
Once 12V at pin 86 and 0V at pin 85 on foglight relay are verified, measure foglight pin 87. Should be 12V. Pin 87 powers the foglights.
Does the lamp on the foglight switch light up? Is the lamp on the foglight switch good?
