Fog light have a mind of there own!

ok, i have a 00 mustang gt. and ive noticed that when its cold, or when i use my high beams, they wont come back on. if its cold once the car warms up, they'll come back on. any ideas, ive checked wireing, and every thing looks like it checks out.

If not a relay then I would say bad grounds at relays or switch.

They will never come on with the high beams unless you wire them differently. The system isn't setup to use foglights and high beams, because technically, it's illegal. But so are HID retrofits in most places.

EDIT: sorry I didn't read the thread correctly the first time, so my post above doesn't really relate. I say check the grounds first, then then the relay as mentioned.

If it weren't for physics and law enforcement, I'd be unstoppable.
