Fog lamps - no voltage
I am not getting voltage to either front lamp. Headlights on, low beam, indicator light is on, but no voltage. I surmise the fuse for the lamps is listed as "front lamps" (#15 in manual). 30 amp fuse looks good (rear lamps work, i.e. back-up lights).
Next step suggestion?

Old fart with a wrench
That's the only one I've got. I thought it would help. Guess not.

From the 93 FSM:
This relay may be there on a 92 but I have a 95 with no fog lights so couldn't check for you.
Foglight Relay Behind left head light, on wheelwell.

Assuming you have an XJ the problem is in the fog light switch itself. Notorious for it. Much written on this and other forums about it.

Got voltage now. Replacing a 15 amp fuse in the engine bay fuse box now gives me 12v.
But if I hook up directly I fear the fuse will blow again (since only 15 amp for both).
Still wondering about that relay, is this it?
But if I have 12V, then the relay and switch are working, yes?
