Hello,

Cadillac has always had blower issues. Make sure you check both fuse panels first. Your owner's manual will tell you where the fuse boxes are located.

On the older models a resistor module (non-serviceable of course) located under the hood on the passenger side would fail requiring either the owner to replace it or hard wire a new switch.

On yours however I believe the BCM controls the blower motor and you won't find a code if there is an internal problem in the BCM every time.

Blown fuse or a bad BCM should be considered.
