Blower Motor Resistor
The blower motor resistor contains specific resistive traces for each fan speed setting. When the internal thermal fuse or a specific resistive coil for speed 3 fails, that circuit remains open, preventing the motor from spinning at that specific setting while allowing others to function. High speed (4) remains functional because it typically utilizes a direct 12V feed that bypasses the resistor block.

Blower Motor Resistor Connector Pigtail
High current draw through the blower circuit often causes the plastic connector housing and metal terminals at the resistor to overheat and melt. This leads to intermittent contact or total circuit failure for specific speed pins. Replacing the pigtail alongside the resistor ensures a low-resistance connection and prevents premature failure of the new component.

HVAC Fan Speed Control Switch
If the resistor and connector are verified as functional, the internal copper contacts within the dash-mounted rotary switch may be worn or carbon-tracked. This prevents the signal for speed 3 from being sent to the resistor assembly.
