The Dorman 901-351 is manufactured to match the look and function of the original equipment on many Ford, Lincoln and Mercury models from the early 2000s through the early 2010s. Built from quality materials and supported by Dorman’s product expertise, this switch aims to deliver the same fit, function, and durability as the factory-installed component.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this switch restore normal door and light behavior?\u003c\/h3\u003e\n\u003cp\u003eWhen the jamb switch fails, the car’s electrical system can’t reliably detect whether a door is open or closed.

Installation is straightforward on most applications because it is designed to match OEM mounting and electrical connections.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaces worn or broken original jamb switch to stop false door-ajar warnings\u003c\/li\u003e\n  \u003cli\u003eRestores courtesy and dome light control tied to door position\u003c\/li\u003e\n  \u003cli\u003eDesigned for OEM-style fit and connector compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles will this part fit and how can I confirm fitment?\u003c\/h3\u003e\n\u003cp\u003eThe Dorman 901-351 supports a wide range of Ford, Lincoln and Mercury vehicles including select years of F-Series trucks, Explorer, Fusion, Ranger, and several Lincoln\/Mercury models.
