Standard Ignition 4WD Switch P/N:TCA-37
Standard Motor Products
Standard Ignition TCA-63 4WD switch for the 2005-2006 Ford F-150 and other vehicles controls four wheel drive selection. This electrically operated switch replaces a damaged original unit.
A blown fuse, a wiring fault or the actuator itself can be behind a four wheel drive that will not engage when you select it, so find the cause before buying a switch. If the switch is the cause, this one replaces it.
Made to OE spec for fit, form and function, it is a direct-fit replacement for the 2005-2006 Ford F-150 and the 2006 Lincoln Mark LT, and each takes one.
