Go to the passenger side of the car and you will see some colored caps coming from the condinser. It looks like an aluminum cylinder. Follow the the lines and you will see something that looks like big valve stem caps that you remove to put air in your tires. You will find it there. The colors will be either green or black. You will not be able to hook the servicing hose to the high side so do not worry. There is only two caps on the vehicle that looks like that.
