Oldsmobile/Buick Repair: 1988 Buick Regal 2.8L V6..., electric door locks, low oil pressure

Question
Hi,
My car has a few problems I've been trying to fix. The electric door locks click, but don't work. I've checked the fuses, but no luck there. The dome light won't work either. The cig lighter doesn't work nor does the power antenae. All these have good fuses, relays etc, but no working. I've checked the obvious, fuses and units for power, but no luck. As for the power antenae, it may just be a bad power portion. The cig lighter nozzle is new, but the base isn't. The power locks, i don't know about them. Dome light is the same. Bulbs are good, but can't seem to figure it out because I know nothing about electrical. Also, my engine low oil pressure light goes on after long periods of idling. I change the oil frequently because of this, but do you think the engine is just getting tired? It has 160K miles on it. Any ideas?
Thanks.
