Help your truck's condenser fan come on when the A/C needs it with the Four Seasons switch 35828, a system-mounted A/C condenser fan switch that signals when the condenser fan should run. It fits many trucks, among them the 2013-2014 Peterbilt 220, 2008-2014 Peterbilt 210 and 2008-2014 Peterbilt 320. It is a direct-fit replacement for the listed applications; see the "Vehicles it fits" section for the full list.
The condenser fan helps move air across the A/C condenser so the system can shed heat. If the original switch has failed, the fan may not come on when needed, and this Four Seasons part replaces it.
- Corrosion protection: Zinc coated to resist corrosion.
- Vehicle-specific: Built for specific vehicle applications.
- Sealing parts included: Contains the gaskets, O-rings or seals needed to replace the product properly.
- Easy identification: Color coded so it is easy to identify.
Four Seasons products are engineered and tested with the aim of years of trouble-free operation, and the brand draws on more than 50 years of mobile A/C experience.
Signs this part may need replacing: a condenser fan that does not switch on with the A/C running, weaker cooling at idle or in slow traffic, or a leak at the switch. Diagnose the cause before replacing, because fan motors, relays and wiring can cause the same symptoms. Follow the vehicle service information when installing, including any refrigerant-handling steps it calls for.
