Electrical problem
1999 Cadillac Deville V8 Front Wheel Drive 150000 miles

My daytime running lights work fine but when I switch to put my headlights on for night driving only my parking lights come on.

If it's not a fuse, it could be the headlight switch itself. There is a relay for high/low beam in fuse/relay block on the left front inner fender well. If all these check out OK, it is probably the body control module which is in the trunk behind the rear seat. Hope this helps.
