Answer
Hello,

Without being at the vehicle, it is hard to say about the wipers and I can only give suggestions. Problem could be a bad park switch it the motor which requires replacement. Check the ground at the wiper motor, and yes it could be the wiper switch. The wiper switch is not the handle you use for the wipers and cruise. The switch replacement requires steering column disassembly. That lever you use pulls out of the wiper switch, which is in the column.
I would highly recommend obtaining a factory service manual for the car on Ebay or Craigs. It will save a ton of money n guess work for all repairs.

As for your roof leak--Diagnoses--Nightmare!!! I fixed leaks on these new. Rarely were they leaking where you thought they were. Sealing could create more problems if the problem is plugged drain tubes.
See if you can get a 19996 Deville body manual. The service manual may cover the roof, but if not then you need a body manual.
It has been so long since I fixed one f these, but I remember drain tubes diverting water out of the rear 1/4. With all the stuff from trees and in the air in Florida have fallen on the top, I would be thinking drainage as your problem.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
