Every time the driver adjusts the cab's temperature control, the Bergstrom HVAC Blend Door Actuator is what physically moves the blend door to mix heated and cooled air to the setting requested. The Bergstrom 651258 mounts using the same bracket and electrical connector the actuator it replaces used. A motor inside rotates through a set arc, and a slipping motor can leave the blend door stuck partway, delivering air too hot or too cold regardless of the setting. Replacing a slipping actuator restores full control over cab temperature instead of a system stuck delivering one air mix.
