Hi, Mike and Marty,

Thanks a lot for your input.

Actually, I have spent past a couple of hours fiddling with the AC and ended up putting another can of Freon in and wasting "gallons" of gas. Yes, I tried to bleed a little but ended up bleeding to the point the AC cycling every 2 second again. No choice that I had to put another can in. For some reason, it took quite while to finish one can. This time, it read 25-30 when fan was on low to high (AC on) and 70 when AC was off (I guess I bled more than I put in). I measured the pressure of V70 with working AC. When the fan was on High, initial reading was 40 and gradually decreased to around 30 to 35, and it took more 20 minutes to get to the cycling point when the fas was on high. For my 850, when the fan was on the highest, the AC never got to the cycling point (the pressure never decreased below 25), though tonight is cool (around 70F) and it was freezing cold in the car. It did cycle when the fan was on the second highest (took a very long time). It cycled very frequent when the fan was on low. Why?

I will keep an eye on my AC and hope it is just age related leak and will let you know what it is going on.

Thanks again.
