Call Of The Week - Ron Ananian, The Car Doctor

  • Vehicle: 2008 Honda Ridgeline

  • Issue: Blower fan and AC stop working after restarting the car (typically after refueling)

  • Behavior:

  •  

    No blower, no AC compressor
    • Comes back on after driving or waiting

    • Happens intermittently

Most Likely Cause:

  • Blower Motor Power Transistor (Resistor Module)

    • Controls blower speed and provides ground

    • Common failure point on this vehicle

    • Failure prevents both blower and AC compressor from working 

Recommended Action:

  • Replace the blower motor power transistor

    • Located under dash, by blower housing

    • Use OEM or Denso for reliability

Optional Diagnostics:

  • Check for 12V at white/blue wire (blower power)

  • Test blue/black wire for ground (from transistor)

  • Bypass transistor ground to confirm blower motor works
