Beck/Arnley designs its parts as direct replacements for OE applications across foreign nameplates, with close attention to form, fit and function. Its product specialists work with a trusted global sourcing network to supply OE-quality parts that meet Beck/Arnley's own requirements and specifications.
- OE form, fit and function: matches the original switch so it can take its place on the listed applications.
- Application-specific: built for particular vehicles, as shown in the "Vehicles it fits" section.
- Diagnose first: Beck/Arnley recommends professional diagnostics for a successful repair.
- Check the whole circuit: test the cooling fan motor's current draw, the control module or relay, and the electrical wiring and connectors.
Signs this switch may need replacing include a cooling fan that never comes on as the engine heats up, a fan that runs all the time, or engine temperature that climbs in slow traffic. The fan motor, relay and wiring can cause the same symptoms, so confirm the cause before you replace the switch.
