sorry to say, but your first mistake, was taking it into a dealer. You already read on here that is the IC pump.
You see the dealer is going to take the supercharger apart,and then there's envelope over about 100 other things that they can take apart and destroy for you. If your car is the same when you get it back you will be one out of 1764. That everything turned out okay,, being that the Chrysler dealer has it, go to that Chrysler dealer asked to talk to the mechanic is working on your car. Tell him it's the IC pump and if you replace that you would appreciate it, if it's not the IC pump tell him you'll buy him lunch for a week. When he finishes the IC pump take your car be happy,,Because 99.9% of the time that is the problem and it will be fixed. jim
