Question about 1998 Pontiac Grand Prix
I've been having this problem for a while, my day time running lights work fine but as soon as it gets dark out they turn off and the only lights I can use are my fog lights, low beams and high beams both don't work. I replaced the multifunction switch because the gray plastic part the slides into the wire harness was starting to melt on one side. This fixed the problem for a few months, but then it slowly started happening again, only working sometimes, and now they're not working at all again. What could be causing this problem?
If changing out the "multifunction switch" worked for a while, and some plastic is being heat damaged, I would suspect a poor connection in the wire harness where it terminates into the switch. If a connection is reduced because of broken wire strands or dirty connections, the remaining capacity (of the wire strands or smaller area of contact) must take the full load being demanded by the lighting system, causing the poor connection to get hot, possibly arc and get worse or fail completely in a very short time. I would first try an Electrical contact or switch cleaner and thoroughly clean out the assembly, while checking for loose or cracked connectors. Follow all safety precautions for the cleaner spray, available at auto parts stores.
Try to determine if the switch area is getting enough air flow for cooling.

There is a 10amp fuse located in the fuse box under the R/S instrument panel end cap cover.
Open the passenger door, remove the cover, if I remember correctly it is held in place with clips.
The Illumination fuse probobly blew when you were working on the multifunction switch, it happens.
Good luck, let me know if there is any thing further.

Believe it or not, but it was a bad ignition switch. I the switch apart and found about 3 different and one in particular that were burned pretty bad. Must have been the circuit that controls the blower and DRL? Found the solution on another blog. I put a new switch on in about 1.5 hours. I does take a couple special tools, very small female torx sockets. Other than that pretty easy.
