I have 95 mustang and my fog lights are not working at all. And recently my headlights would stay on for five minutes then they turn complete off while I'm driving. Most of the time I have to turn on my high beams. My park lights and tail lights are still on. I check all bulbs they are good. I check my headlights switch which is good shape. I went to auto zone one of the worker told me that I need a fog lamp relay. I don't know if this part going to work or not. Please send any suggestion and information so I can fix this problem.

SOURCE: high beams wont turn on.

First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)

check for voltage at the high beam switch when high beams are turned on.
