No DRL's or Side Ambers

I have a 1999 Grand Prix GT and the DRL's and amber side lights don't work during the day but the night sensor turns everything on at night. I have not disconnected anything to make this happen but we are looking at selling the car and want to be able to have them on if it comes up. I must say that I do like the look of it though.

Any suggestions?????

Under the hood in the electrical center located on the passenger side, there's a fuse in there labeled DRL (Daytime Running Lamps). Check that fuse.

There is no fuse for the DRL's under the hood, just in the glove box. I have checked it and replaced it but still have the same problem.
