so of it is an amp prob. what contacts should I check- and how do I test the contacts while cc is on (if im driving and i put it on) cuz it dont work standing still.....

if it is an actuator problem, I will go to the yard and pull another- test to see if that fixes the problem- however I would like to be positive that is the issue before I buy a junk part I cant return

Which begs the question- how can I find out where the problem is?
