Wiper Switches

Tom's Offroad carries wiper switches, wiper arms, wiper blades, wiper motors, and wiper linkage components for the 1966–1977 early Bronco. The factory wiper system used vacuum-operated wipers on early models before switching to electric wipers in the early 1970s. Replacement switches and upgrade components for both systems are available.

The early Ford Bronco transitioned from vacuum-operated windshield wipers to electric wipers during the 1971 model year. Vacuum wipers on the earlier trucks slow down under hard acceleration due to reduced manifold vacuum, which is a common complaint. Many owners of pre-1971 Broncos convert to electric wipers for consistent performance. Conversion kits are available that use the factory wiper arm mounting points.

Replacing the wiper switch on an early Bronco involves removing the switch knob, unbolting the switch from the dash panel, and disconnecting the wiring. Installation is the reverse process.

On vacuum-wiper early Broncos, slow or non-functioning wipers are usually caused by a cracked or disconnected vacuum line, a failing wiper switch, or a worn vacuum motor. On electric-wiper trucks, a blown fuse, faulty wiper switch, corroded wiper motor connections, or a worn wiper motor are the typical culprits. Check the fuse first, then the switch, and finally the motor before replacing components.

The early Bronco uses a standard hook-style wiper arm attachment common to most American vehicles of the era. Replacement wiper blades and arms in the correct length for the early Bronco's windshield are available through specialty parts houses. Tom's Offroad also carries period-correct replacement wiper arms and blade assemblies for trucks undergoing a thorough restoration.
