MultiFunction Switches used on '92-up Ford trucks, other Ford products, & other vehicles including the Nissan Quest. There are electrical & functional variations, including the Hazard switch & the presence of cornering contacts or a rear interval wiper control. The stalks are interchangeable, but disassembling the switch requires patience & precision to keep all the tiny parts in-place. '92-97 F-series/Broncos use Motorcraft SW5591.

'97~03 trucks are also known to have a short wiring harness takeout for this switch, resulting in connector terminal pullout if the wheel is tilted fully down. The repair is to pull (hard) some slack into the wires, then insert the terminals into a new connector shell.
Upper Connector Motorcraft WPT-611
Lower Connector Motorcraft WPT-179
