Buck, according to a Sanden troubleshooting chart that I find useful, when both high and low sides are high, it typically means insufficient condenser airflow and/or an expansion valve that is not working properly (or its intake screen is somewhat plugged - it it has one of those).

Of course, you don't really need a chart when you've got Griff posting here, but it does come in handy, and breaks down the basics of how mobile a/c systems work.
