Nissan Repair: Electrical - Headlights not working, daytime running lights, high beams

Question
Love my 1990 Maxima (brought in CDN)  But problems began with my daytime running lights working intermittently, eventually they stopped working, sometime later the headlights stopped functioning, finally high beams stopped working too. FYI just replaced my battery recently. Fuses checked and they look OK.
Could it be a switch problem or a rely? Appreciate any help.

PS. Radio can't hold a preset station setting. And the climate control fan/blower won't shut off-runs at maximium speed.  

Answer
Diane,

It could be your rely, but if you just changed the battery then it's got to be an electrical problem.

Your best bet is to take it to a shop and have it looked over.  Sounds like a major or maybe minor electrical problem.

Hope it's NOT major.  Best of luck.. I know this wasn't much help.  But not much I can offer, since you have already changed your battery.

Good luck
