It fits many vehicles, among them the 1996-2024 Chevrolet Express 2500, 1996-2023 Chevrolet Express 3500 and 2009-2020 GMC Savana 4500, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
The catalog lists this part under both the Switch and HVAC Blower Motor Resistor names. It draws on Four Seasons' more than 50 years of mobile A/C experience, and the brand engineers and tests it with the aim of years of trouble-free operation.
- Vehicle-specific applications: made for the listed applications.
- OE-style connectors: for the electrical connection.
- Quality contacts: designed to provide proper conductivity.
- Precision engineered.
Signs this resistor may need replacing include a blower that runs only on its highest setting, or one or more fan speeds that no longer work. If a failed resistor is the cause, this unit replaces it. Diagnose the circuit first, because a faulty control switch, blower motor or wiring can cause similar symptoms.
