What Does the B1264 Chevrolet Code Mean?

Under normal operation, the panel/defrost and floor door actuator motors are supplied voltage or ground through the circuit, depending on desired actuator rotation, by the Electronic Automatic Temperature Control (EATC) module. The EATC module then supplies the appropriate voltage or ground to the other side of the actuator motor. The panel/defrost and floor door actuator feedback resistors are supplied a ground and a 5-volt reference voltage from the EATC module. The EATC module reads the voltage on the circuit to determine the actuator position by the position of the actuator feedback resistor wiper arm.
