AboutRob Painter Expertise 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?

Question can you tell me where to locate the blower motor resistor for this car. the blower will not shut off and i have narrowed it down to this but cannot locate.
Answer Hello,
The old very very common problem going back to the eighties that Cadillac and only Cadillac had was that the heater blower module would internally fry. Located commonly under the hood on the passenger side these printed circuit modules could only be replaced and not repaired to the tune of $300-$400 bucks!
What I commonly would see even on 82' Eldorados would be one or two seperate toggles installed under the dash (the second being an inline resistor for a lower blower speed)to operate the blower to keep the battery from going dead. Yes, this sounds slip-shod, but it is the best way of repair other than going to Cadillac, getting ripped for having a new part installed that is doomed to fail again.
