The turn signal switch on a 1994 Wrangler is housed inside the steering column. The switch is connected to a detachable stalk that controls the switch. Over time, the connectors on the switch can wear, causing the switch to activate when the stalk isn't moved, or the signal may fail to activate when the stalk is moved up or down. Although the individual components of the switch can't be repaired or serviced, the switch itself can be replaced. You can accomplish this task yourself if you have the right tools.
