Have a '90 NewYorker that had the battery go completely dead. Replaced the battery. New one went totally dead inside of 24 hours. Went to fuse block under hood and found that the fuse labeled "REAR WINDOW DEFROSTER" showed a SHORT to ground. So, I removed it to get the car running temporarily. That worked, but when it was removed, interior lights (dome) went out. Power windows and locks quit. So did SOME of the dash stuff, radio. I replaced the under-hood fuse, and went looking in the interior fuse block for where the trouble might be. When I pulled DOME LIGHTS fuse, the short goes away. But when I did this, all KINDS of strange stuff happened. I fully expected JUST the dome lights to go away. But it also took out the MANUAL control of door locks (they still work fine when the ignition is ON, and they work "automatically" as always when the car exceeds 15MPH or so). But the door locks DO NOT work when ignition is OFF. It also took out the radio (again).
Any ideas of how to fix, short of ripping the whole harness out? Thanks in advance for any help.
