What is the purpose of the Cruise Control Module system on Buick Skylark?

This cruising speed control system is optionally available on certain models and allows the driver to maintain a constant highway speed without the necessity of continual adjustment of foot pressure on the accelerator pedal. The system employs a servo unit connected to the intake manifold, a speedometer cable-driven regulator and various switches. An override capability is built in. Any malfunction in the performance of the system should first be checked out by inspecting the fuse, the security of the leads and terminals, and the vacuum pipes and connections. The following adjustments should then be checked and if necessary altered to conform to those specified. The servo operating rod which connects to the carburetor throttle linkage should be adjusted. The regulator can be adjusted by turning the orifice tube in or out (never remove it as it cannot be re-installed). If the vehicle cruises below the engagement speed, screw the orifice tube out. If the vehicle cruises above the engagement speed, screw the orifice tube in. Each¾ turn of the orifice tube will change the cruise speed by about 1 mph.Tighten the locknut after each adjustment. The brake release switch contacts must open when the brake pedal is depressed between ¼ and ½-in measured at the pedal pad. The vacuum valve plunger must clear the pedal arm when the arm is moved A inch measured at the switch. The column mounted engagement switch is non-adjustable, and is serviced only as part of the complete turn signal lever assembly. Faulty components should be replaced as complete assemblies after disconnecting electrical leads, vacuum hoses and control cables from them as necessary.

Buick Skylark Cruise Control Module

The Cruise Control Module for Buick Skylark allows the car to maintain a steady speed so that drivers can rest their right foot and focus on traffic more. The Cruise Control Module acts like a brain that reads the signals from the necessary sensors. Further, it will open or close the throttle as per the mph selected. As the throttle style Cruise Control Module of early Skylark models was vacuum based, it applied the engine's vacuum to pull a cable that connects with the carburetor. This made it easy to use and simple, but it was not fast to react when the car faced a hill. As electronics improved, Buick switched from vacuum hoses to electric motors for its Cruise Control Module, which improved response and eliminated many leak-related failures. In later production years, a drive-by-wire design incorporated throttle control with the engine computer, removing a stand-alone Cruise Control Module while providing smoother speed control and improved fuel use. While all the different types aim to do the same thing, the different units operate differently. For instance, vacuum units depend on pressure, servo units on dedicated motors, and drive-by-wire units on digital signals. Locating the right parts for a Buick Skylark and diagnosing speed holding problems relies on the installed generation.

Each OEM Buick Skylark Cruise Control Module we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
