Ok first you will need a digital multi meter ok. Then you need to find the cruise control actuator under the hood this is where the control cable comes from. and unplug the 4 pin harness from it. Now you will need to make a couple of jumper wires one to reach the battery possitive and one to go to ground ok. Then take and ground term 1 and put power to term 2 listen for a clicking sound. If it doesn't click then replace it. If it does click then go to the next step. Here is a pic of the connector.
Put power to term 4 and gound term 3 you should hear the motor run now take it to half throttle and you should still hear the motor run now go to full throttle and motor should stop running. If this works fine then go to the step.
Put power to term 3 and ground term 4 now you should not hear the motor, now take it to half throttle you should hear the motor and you should hear it a full throttle. Here is a pic of the 4 pin connector and then I will include a pic of the pin test for the throttle possitions ok. If all this works then the actuator is fine, if any of this does not work then the actuator needs replacement ok.
Here is a pic of the pin tests to see if the motor runs when it is suppose to ok.
Let me know how this goes and we will test what is next in line ok. Thanks and have a great day.
