What symptoms indicate the blower resistor needs replacing?

If your fan operates only on the highest speed, or certain speed settings won’t engage, the resistor module is a likely culprit. You may also notice inconsistent fan behavior or no fan operation in some modes.

• Only high fan speed works while low/medium speeds fail.
• Intermittent fan operation or complete loss of blower control.
• Burned smell near the passenger footwell or visible heat-damaged resistor housing.
