What Does B1267 Mean?
This code indicates the Body Control Module (BCM) has detected an electrical fault in the right side air intake servo motor circuit. The servo motor controls airflow direction or blend doors in the HVAC system for climate control. The BCM has identified either an open circuit, short circuit, or abnormal resistance/voltage in the wiring or motor that prevents proper operation of the right side air intake actuator.
Common Causes
45%
Failed right side air intake servo motor/actuator with internal electrical fault or mechanical binding
30%
Damaged wiring harness, corroded connectors, or loose terminals in the servo motor circuit
15%
Defective BCM with internal driver circuit failure for the servo motor
10%
Blown fuse or faulty relay in the HVAC servo motor power supply circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of the right side air intake servo motor connector behind the dashboard/glove box area for corrosion, damaged pins, or loose connections. Check for proper seating and terminal tension.
2
Step 2: Using a multimeter, test voltage supply at the servo motor connector with ignition on. Verify presence of battery voltage (typically 5V or 12V reference depending on manufacturer) and ground continuity. Check for voltage drops exceeding 0.5V.
3
Step 3: Disconnect the servo motor and measure its resistance across the motor terminals. Compare readings to manufacturer specifications (typically 20-200 ohms). Test for shorts to ground on all circuits with motor disconnected.
4
Step 4: Command the servo motor to actuate using bidirectional controls through the scan tool while monitoring live data. Listen for motor operation and observe current draw. Normal operation typically draws 0.3-1.5 amps depending on design.
5
Step 5: If motor operates correctly during actuation test, inspect the blend door or air intake door for binding, broken linkage, or obstruction preventing free movement. Check for broken mounting tabs or seized pivot points.
6
Step 6: After repairs, clear codes, cycle ignition, perform HVAC self-calibration procedure if available, and verify proper operation of all climate control functions with no code return.

The most common cause of B1267 (Servo Motor Airintake Right Circuit Failure) is: Failed right side air intake servo motor/actuator with internal electrical fault or mechanical binding
Typical repair costs for B1267 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is safe to continue driving as it only affects climate control comfort features, not vehicle safety systems. Repair can be scheduled at convenience, though climate control functionality on the right side may be limited or inoperative until resolved.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1267 to identify the root cause.
