Having problems with your 1998 GMC Sonoma ?

My night time head lights wont come on. Ive changed multipurpose switch and lights still wont come on. Day time lights run in the day just fine, Earlier when my my lights started going out at night. I could slam my door and they come on for awhile. Now they dont come on at all at night. Ive changed all the relay switches in the dash board and no luck. could it be a computer problem or wires or just expensive all around??
