OBD-II Body Error Code B1207: How to Fix It

Q: Can I drive with error code B1207?

Yes, you can drive safely with B1207, but the blower motor running continuously will drain your battery faster and may cause premature wear of HVAC components. Fix it promptly to avoid bigger problems.

Q: How much does it cost to fix B1207 error code?

If it's just a faulty relay, the cost is $15-30 for the part plus labor. A blower motor resistor costs $25-60. More complex wiring or module issues can cost $200-500 depending on your vehicle and labor rates.

Q: Will B1207 cause my car to fail inspection?

B1207 is typically not an emissions-related code and shouldn't cause inspection failure. However, some states may fail vehicles for any stored diagnostic trouble codes, so check your local requirements.

Q: What causes the blower motor to stay on constantly?

Common causes include a stuck blower motor relay, failed blower motor resistor, shorted wiring in the HVAC circuit, or a malfunctioning climate control module sending continuous power signals.

Q: How do I prevent B1207 from happening again?

Regular HVAC system maintenance, keeping cabin air filters clean, and addressing electrical issues promptly can help prevent B1207. Also avoid forcing HVAC controls if they become stiff or unresponsive.

Abstract

OBD-II error code B1207 indicates your vehicle's blower motor circuit is stuck in the 'always on' position, meaning the HVAC fan runs continuously even when the system should be off. This automotive issue typically stems from a faulty blower motor relay, stuck blower motor resistor, or wiring problems in the climate control system.
