2000 Ford Taurus Battery Drain - - After the car door is opened the wipers still work, power windows still work, power seats still work, radio still works, etc. Shouldn't the battery power disengage to these components after the driver car door is opened? Just purchased this vehicle. Door switch appears to be working due to light coming on in dash when door is opened.

Using a test light with all doors closed everything in the car off; disconnect your black battery cable then: connect a test light between the battery post you just removed the cable from and the cable you removed; the light should light. this is your short (leak) then remove fuses until you find the fuse that causes the light to go off your problem is in that circuit.
