B295D Code - Right Blend Door Potentiometer Feedback Short to Ground
Quick Answer
Under normal operation, to rotate the blend door actuator, the Electronic Manual Temperature Control (EMTC) or Electronic Automatic Temperature Control (EATC) module supplies voltage to the actuator motors through the door actuator clockwise circuits, and supplies ground through the door actuator counterclockwise circuits. Common causes include Faulty Right Blend Door Actuator, Right Blend Door Actuator harness is open or shorted, Right Blend Door Actuator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B295D Description
The actuator feedback resistors are supplied a ground from the EMTC module or EATC module by the door actuator return circuits and a 5-volt reference voltage on the door actuator reference circuits. The EMTC module or EATC module reads the voltage on the blend door actuator feedback circuits to determine the door actuator position, by the position of the actuator feedback resistor wiper arm.
What are the Possible Causes of the DTC B295D?
- Faulty Right Blend Door Actuator
- Right Blend Door Actuator harness is open or shorted
- Right Blend Door Actuator circuit poor electrical connection
- Faulty Electronic Manual Temperature Control (EMTC) or Electronic Automatic Temperature Control (EATC)
How to Fix the DTC B295D?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0

Frequently Asked Questions about B295D Code
1. What does the OBDII code B295D mean?
The code B295D indicates a "Right Blend Door Potentiometer Feedback Short to Ground," which typically signifies an electrical issue with the blend door position sensor in the HVAC system.
2. What are the common symptoms of code B295D?
Symptoms may include improper temperature control, difficulty switching between hot and cold air, or unusual noises coming from the HVAC system.
3. What causes the B295D code to appear?
The code can be caused by a shorted or damaged wiring harness, a faulty blend door actuator, or issues with the potentiometer feedback circuit.
4. How does the right blend door potentiometer work?
The potentiometer monitors the position of the blend door to ensure the proper mix of hot and cold air is delivered into the cabin.
5. Can code B295D affect other vehicle systems?
It primarily affects the HVAC system, but persistent electrical issues could potentially drain the battery or interfere with other components in rare cases.
6. How can I diagnose the B295D code?
Start by inspecting the wiring and connectors for damage or corrosion, then test the blend door actuator and potentiometer to ensure they are functioning correctly.
7. Is it safe to drive with the B295D code present?
Yes, it’s generally safe to drive, but your HVAC system may not operate properly, which can be uncomfortable in extreme weather conditions.
8. How do I fix the B295D code?
Repairs may include replacing the blend door actuator, repairing damaged wiring, or addressing a faulty potentiometer.
