if you have 98 coupe....do this
1. you have to get in the car without opening door, so if you have alarm, disarm it, but do not open n e door. however you can open the trunk, and gain access to the vehicle.
2. once you're inside of the car, honk really short twice. then insert key, put it in on position.
3. then turn your headlight on, and open both of your sun visor/open mirror so they light up. then lock each door one by one. do not lock them all with power lock.
4. now get out of the vehicle the same way you have entered.
5. close the trunk.
6. wait till car honks twice back at you. and everything will unlock by itself.
7. get in the car through driver's side door, turn on your fog, then turn off your headlight.
8. TADA! your foglight stays on without headlight.
9. enjoy the awesomeness of fog without headlight.
