Answer
Hi Randy,

First, buy a cheap test light. You can probably get one at a parts store for $5.
Make sure you have power going to the blower motor and that the ground is good.
Then go to the fuse box and check both side of the fuses for power. The blower motor fuse can be listed as A/C or heater. It's been too long since I worked on a 1986 Caddy.
You need the key on for checking the fuses for power, because the blower motor is on switch power. If you find a 20 or 30 amp fuse with power only on one side, pull it out. I am sure you will find the blown blower motor fuse. Put a new one the same amperage and it should take care of your problem. Don't know off hand what it will be labeled.

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?
