Question
changed blower motor on a 1997 dev the motor comes on some times it will not compresur is working fine.what may it be[ hot ]. in ky...

Answer
Hello?

This is one of two very common smptoms that Cadillac was notorious for. One was over heating, the second, blower issues dating as far back as 1981.

One would think that the factory would have addressed these issues in more than 20 years.

You have one of two possibilities here and I would recomend a local service center (not a dealer) to diagnose.

If so equipped, could need a new blower resistor module or the other could be a bad computer.

Thanks for the rating, but I am very concerned. If this wire appears to have gotten hot where the lead fell off--DISCONNECT THIS ALARM SYSTEM NOW!!!!!

I am concerned because if this statement is correct, you have the potential for a car fire!!!!

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?
