the lamps have poor circuit boards in them may have to replace. the fuse together inside over time. that is why you see so many of them out. the stock style replacement lenses are really cheap.

I had a similar problem. I had to ever so slowly turn on the parking lights and then turn off the headlights. It's the switch. Get a torex wrench and take out the 4 screws holding on the dash bezel. Unplug the light harness, slowly and with patience. 4 little screws hold the switch onto the bezel. Take them out, don't lose them. With a very small blade screw driver you can slowly pry open the switch. One inside you will find grease and goo from 1990. Look for corrosion on the switch plate and fingers. Clean gently with contact cleaner and maybe mild steel wool. You have dirty contacts. This is a 15 minute job the hardest part is finding the torex and then patiently taking the switch apart. Good luck.
