those housings are 'xenon'(oem term) or 'hid' (aftermarket term)

given the age of the car, my first guess is that the bulbs are going bad. iirc, they should be d4s bulbs. if you take one out and look at the little capsule inside, if it's almost entirely black, it's a good first step(they start clear, and then slowly get blacker as time goes on)

the fact that the height adjuster in the car works tells me that the previous owner spent time doing it right, though the boomerang not working is suspect...
