Thanks Guys, I hope that it is the expansion valve. I'll have to use the uv method. I don't see any red or oily spots. It is still cold in Louisville and it is not going to make condensate! I really don't look forward to removing the dash. I'm 70 or 80 pounds overweight and it will be tough. I love this car and it is probably the overall best car I've ever owned. I doubt I could get much for it anyway with no air. Car has 235K, new tires, radiator, and alternator. 32 mpg and a comfortable car. I drive 500-600 miles per week and I like the comfort. I've had diesels for 21 years and love the economy and dependability of them. Larry this car was fitted with 134 from the factory. Ernie
