I have a 2004 Toyota Sienna All Wheel Drive LTD XLE. The A/C is hot on the drivers side, but cool on the passenger side ! Is there an easy fix for this ? I also have lost my power steering. There are drips spots on our driveway. So I put in a container of sealer. It came back for a short time. Now it is like driving a truck. Any quick fixes for this other than replacing the pump ?
