B1969
Low Severity (Level 2)A/C Clutch Magnetic Control Circuit Failure
B1969 usually means a/C Clutch Magnetic Control Circuit Failure.
Can you still drive with B1969?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $50 – $800
Severity Level 2 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Blower motor not working or only working on certain speeds
- A/C or heat output inconsistent — temperature won't adjust
- Warning light or message on dashboard related to the climate control / HVAC system
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed blower motor — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the climate control / HVAC system circuit
- Blown fuse for the climate control / HVAC system circuit — check before replacing components
- Faulty control module driving the blower motor
- Loose or corroded ground point shared by the climate control / HVAC system
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($40-120 at shop, free at auto parts store for basic scan)
- Visually inspect the climate control / HVAC system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $102 diagnostic fee at shop)
- Replace blower motor if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($50-800)
- Check and replace any blown fuses in the climate control / HVAC system fuse circuit — if fuse blows again, there's still a short that needs to be found ($2-12 for fuses)
- Perform a wiggle test on the climate control / HVAC system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-115 diagnostic labor)
