Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Servo Unit
Turn ignition switch to "ACCESSORY" or "ON" position. Move slide switch to "ON" position. Momentarily disconnecting and connecting double connector at servo terminals should produce a clicking sound in servo. If no clicking sound heard, replace servo. Without removing either connector at servo, place a test lamp probe to black (with tracer) wire terminal of servo. Place other probe to a good ground. Block front wheels, raise rear wheels and drive rear wheels to 35 MPH. With both ignition switch and speed control switches in "ON" position, depress and release speed set button. Speed should increase above 35 MPH and test lamp should remain on until brake pedal is depressed.
