Code B0195 GMC Description

The Blower Motor Control Module is an interface between the Heating, Ventilation, and Air Conditioning (HVAC) Control Module and the blower motor. The blower motor speed control from the HVAC control module, battery positive and ground circuits enable the blower motor control module to operate. The HVAC control module provides a Pulse Width Modulation (PWM) signal to the blower motor control module in order to command the blower motor speed. The blower motor control module transfers the PWM signal into a corresponding blower motor voltage. The voltage resides between 2-13 V and changes linear to the height of the PWM signal.

Frequently Asked Questions about B0195 GMC Code

1. What does the OBDII code B0195 on a GMC mean?

The B0195 code indicates a problem with the Front Blower Motor Speed Circuit, specifically that it is reading a low voltage.

2. What are the symptoms of the B0195 code on a GMC vehicle?

Common symptoms include reduced or no airflow from the HVAC system, inability to control blower motor speed, and possible climate control malfunctions.

3. What causes the B0195 code on a GMC?

The code is typically caused by a faulty blower motor, a defective blower motor resistor, wiring issues such as shorts or open circuits, or a malfunctioning HVAC control module.

4. How can I diagnose the B0195 code?

Start by inspecting the blower motor, resistor, and associated wiring for damage or corrosion. Use a multimeter to check for proper voltage and continuity in the circuit.

5. Can a blown fuse cause the B0195 code?

Yes, if the fuse for the blower motor circuit is blown, it can cause the circuit to show low voltage and trigger the B0195 code.

6. How do I fix the B0195 code on a GMC?

Repairs may include replacing a damaged blower motor, replacing the blower motor resistor, repairing or replacing damaged wiring, or reprogramming or replacing the HVAC control module.

7. Can I drive my GMC with the B0195 code active?

Yes, you can drive, but without a functioning blower motor, you may experience discomfort due to lack of heating, cooling, or defogging capabilities.

8. How much does it cost to fix the B0195 code?

Repair costs can range from $100 to $500, depending on whether the blower motor, resistor, or control module needs replacement.

9. How can I prevent the B0195 code from occurring again?

Regularly inspect and maintain the HVAC system, including the blower motor and its wiring. Address any electrical issues promptly to avoid circuit failures.

10. Will clearing the B0195 code with a scanner fix the problem?

Clearing the code with a scanner will reset it temporarily, but the underlying issue must be resolved to prevent the code from returning.
