Question
There is a toggle switch right next to the alarm button under the dash, what is this for? Also, on the air, cannot get the temperature buttons to change to lower the temp or get it to blow cold period. This is a 1991 Cadillac Brougham with 95,900
Hello,
What you have is a very poor installation of an alarm. In other words, whatever someone paid for the alarm was far too much!
The first place a thief looks to turn off the alarm is below the dash. Installers that have never seen a stolen car are ignorant as to what a thief would do. Infact, many of these ignorant goof installers think a thied needs keys to the car to start the engine.
What the toggle is for is a valet switch to turn off all functions of the alarm with yhe ignition on.
That switch needs to be hidden.
As for a/c problem cannot help you.

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?
