What has to be done to fix this problem

I had a problem with the interior lights making the battery go dead. I thought the battery was at fault, 5 years old. I replaced the battery and still had the problem. After doing some research: I learned the culprit was, most likely, the LCM. I replaced the LCM $300.00. Now fuse #18 keeps blowing. Is there a common location for a possible short in these models? I made up a jumper with a light bulb and bridged the fuse location. With all of the doors, trunk lid, vanity lights off, and glove box shut: the light is on full brightness. Nothing I do by opening the doors or anything with the interior lights has any effect. That light stays on. There must be a dead short somewhere! Hopefully: there might be a common place in these models where I can look. I hate to unload this piece of junk like it is, because this would hurt the resale value. It's been one electrical malfunction after another. Now I know that all of those Crown Vic's weren't at the dealership for routine maintenance, but for electrical problems. The Panther platform is one of the toughest, but: when it comes to wiring a vehicle: the people at Ford don't know squat about how to wire one!

Is this a common problem? With only 37,000 miles on the car should these parts be failing? Anyone else experiencing this expensive issue?

Thanks

MY engine light came on right after an oil change. I took my car back and they told me and showed me 4 "spark plug" like things under my car and told me I had 4 oxygen sensors that were not functional on the diagnostic test, so they replaced them charging $129 each $240 in labor.

the fuse for the dome light blows if the fuse does not blow the battery discharges

message board states " change engine oil soon". I recently changed the oil.

I do my own oil change.
