Did you check the actuator connector? That is by far the most common source of this problem.

If the indicator light is not blinking and it is not a poor connection at the actuator connector or wiring, then it is either the switch on the stalk, the cruise control ECU, or the actuator itself. Download the '94 Camry FSM from the link stickied at the top of this forum and diagnose as shown on pages BE-202 (switch), IN-36 (CC ECU), and BE-190, BE-192, and BE-196 (actuator).
