Heater Motor Blower Resistor Fan Resistor Control Module Compatible With 2003 To 2007 H2 3GSH19E624CA 3GSH19E624CA Overview This blower resistor control module replaces a failing heater motor resistor to restore multispeed control of the HVAC blower in compatible 2003 to 2007 H2 vehicles. It is designed to match the original part numbers 3GSH19E624CA and 3GSH19E624CA for straightforward fitment. Key benefits Restores blower speed control: Fixes conditions where the heater or A C fan runs only on or loses some speed settings. Direct fit replacement: Designed to match factory mounting points and connector layout for a straightforward swap. Reliable electrical connection: Built with durable terminals and a compact housing to maintain consistent performance under normal vehicle conditions. Saves time and effort: Replacing the resistor is a targeted that avoids more invasive HVAC work when the blower motor itself is still functional. What it does Controls resistance levels sent to the blower motor to provide multiple fan speeds. Replaces the defective control module that causes fan speed failures or intermittent blower operation. Compatibility and part numbers Compatible with H2 model years 2003 through 2007. Matches part numbers 3GSH19E624CA and 3GSH19E624CA for correct identification and fit. Attributes Function: Heater motor blower resistor control module for multispeed fan operation. Fit: Direct replacement form factor intended to align with original mounting and connector. Material: Durable plastic housing with metal electrical terminals for conductivity and longevity. Size: Compact design to fit within the vehicle HVAC housing in place of the original resistor. Performance: Restores smooth, multispeed blower control when the resistor is the source of the problem. Typical applications a failed blower resistor assembly when the vehicle HVAC fan operates only on the speed. Restore full fan speed range during seasonal maintenance before summer and winter weather. Quick DIY during routine HVAC troubleshooting to confirm blower motor versus resistor issues. Installation notes Basic hand tools and simple disconnect of the electrical connector are typically required. Inspect the blower motor and connector for signs of overheating or damage while replacing the resistor. Use the part numbers 3GSH19E624CA or 3GSH19E624CA to confirm compatibility before installation. This blower resistor control module provides a focused solution to bring back reliable fan speed control in compatible 2003 to 2007 H2 vehicles.
