Cruise Control doesn't work?

Lift the front wheels. Turn on the switch on. When u get to 30 mph set the cruise. Ck there is power on the green or yellow wires when u hit the set button. Then ck. And see if the servo seloniod gets power when u set it. If there is power replace the seloniod.

The seloniod is on the servo. Youll see a seloniod with a 2 wire connecter and a vacuum line to it. Make sure their is vacuum on that line. Lift the car and when u go over 30 mph. Set the cruise and make sure its sending voltage to the seloniod when u set the cruise.

Im sorry but there to many things and circuts that have to be cked. It makes it hard for me to help anymore.

Does the yellow light come on then turn green when u engage?

Try lifting the brake pedal with your foot. Will it engage then?

Remove the lever connector ck for power on the pins where it plugs in. Do u have power?

Volts and yes

Hi the cruise has several things to operate it first go under the hood find the cruise sevo this will have a cable going from it to the throttle same as the accel pedal. Make sure the cable is connected to the throttle not broken if ok. Look at the electrical plug where it plugs into the servo make sure it is secure and has no corrosion or breaks.

At the servo there is a vacum hose make sure this hose is connected to the eng and the servo if yes start eng remove vacum hose from servo make sure it has vacum coming through the hose. If yes plug back in.

Under dash at upper brake pedal you will see two switches mounted on the brake pedal some cars only have one one is for your brake lights one is to shut off cruise when you hit the brake. Make sure the switches are working.

Before you do any of this be positive all fuses are good. Good luck

Off

Sorry the key needs to be on to ck those pins for power. Before that lets check the cpu for cruise codes. Push off and warmer on the a/c panel. When u see all segments light release. Then write the codes down. We will be here.

That is good u know how oper. The cpu some. They are not pins its the flat circut board ck the sodered lines on the board for 12v on one pin?Use the a/c fan speed the low is no and the hi is yes. Hit low until u see bcm inputs? Then hit high for yes. Then keep hitting low button for no until u start seeing c/c on and off, c/c set, c/c coast and resume. It will say all these on the a/c panel. Like cruise set with a 0 next to it. When u hit the set button the 0 will turn into a x and back to a 0 when u release it. This will test all the switch opers. Tohelp u check all the switchs or 1 thats not working
