Thanks Tom & Jim. Evacuated and recharged. Seemed ok for a while, then woulden't cycle back on. Checked pressures, HI & LOW were extreme opposite of what they should be, indicating a stuck expansion valve. This system does not have a replaceable expansion valve. After a while it worked again. Some say theese vehicles had many intermittent electrical problems. The A/C works more than it doesn't work making it difficult to diagnose which I would gladly pay someone to do if it would stay not working! <img src="/forums/images/graemlins/confused.gif" alt="" />
