1996 Ford Bronco Rear Window Defroster Wiring Diagram - Defrost Circuit

This is a wiring diagram for the rear window defrost (defroster) system, uploaded for a 1996 Ford Bronco. The diagram shows power feeds from two sources: the interior fuse panel (referenced to page 13-1) and the engine compartment fuse box (referenced to page 13-4). Power routes through a rear window defrost control module containing a momentary on/off switch, a timing circuit, and switch illumination (tied to instrument illumination, page 71-1). A callout note explains the operation: pressing the momentary defrost switch ON closes the contacts of the defrost relay, and a timing cycle (approximately ten minutes) then applies power to the rear window defrost grid. The circuit continues through several connectors and splices on the right side of the diagram to the rear window defrost grid element, which grounds at the rear of the vehicle. Multiple black (BK) ground wires from the control module lead to chassis grounds, with a reference to "See Grounds, page 10-9." A legend on the right identifies diagram symbols for Component, Connector, Ground, Splice, Page, and Harness. Due to the very low scan resolution, most connector numbers, circuit numbers, and wire color codes are only partially legible.
