SOURCE: blower motor

The blower motor is on the passenger side of the front seats, pull the carpet back and you will see it there. Make sure it's not the little computer sitting right next to the blower instead of the blower. When you turn the temp down to 65 does the little orange colored AC button light up? If not, it's the climate control computer which is sitting next to the blower.

SOURCE: 1999 cadillac deville a/c off low refrig error

I had the same problem. The mechanic could not get the compressor to take in new freon. It has to do with the car's memory. You have to reset it by disconnecting the hot wire from the battery which for thirty seconds. This resets the cars internal memory, so it won't remember that it's out of freon. Reconnect it turn on the car and turn on the air the compressor will start.

92 cadillac deville no heat or air blowing at all


Devilles use a controller instead of a basic blower resistor.
Someone would need to check the blower motor for power and ground, then check the controller mounted in the HVAC box on the firewall.
You may need a shop manual to get the wiring diagrams needed to troubleshoot the system.

Where is blower motor resistor located?


The blower motor resistor on most vehicles are located in the blower motor casing, always replace the cabin filter (if fitted) every year no matter how many miles you've covered.

1999 cadillac deville air wont work


There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.
