RE: Cascadia cab blower motor
Check the blower motor relay in the dash and make sure that it's functioning properly. Pins 85 and 86 will be the coil side which is going to be controlled by the switch. Pin 30 will have constant power and 87 will be the switched power going to the motor. A simple check is to jump across pin 30 and 87 and see if you now have power at the motor. If 30 has power and jumping to 87 still gives you nothing at the motor, you're going to need to check your blower motor relay which will be in the duct work just after the blower motor.
