You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.

The problem is likely your multi purpose signal light switch. If you take the lever and move it from hi to low beam will the low beams come on? It is common for this multi purpose (real expensive ) switch to fail after a period of time! The steering wheel may have to be removed, to change it. The air bags will also need to be disabled so as not to active them while removing the switch.
