Ford Mustang 1994-1998 Repair Guide

Combination Switch


All models covered by this guide are equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, air bag module, steering column or instrument panel, disconnect the negative, then the positive battery cables and wait at least one minute. Disconnecting the battery cables and waiting one minute will allow any residual power in the system to drain. Failure to properly disconnect both battery cables may result in accidental air bag deployment, which could easily result in severe personal injury or death. Also, never attempt any electrical diagnosis or service to the SRS components and wiring; this work should only be performed by a qualified automotive technician.

The combination switch incorporates the turn signal, dimmer, hazard lights and wiper switch functions on the Mustang.


See Figure 1
