Hi All,
Have a 98 v70 with 112k miles. A/C has been great; has not ever needed a charge or leak repaired (odd for 850s and 70s apparently). Anyhow, today while driving along, I noticed the a/c began to blow warm humid air. The a/c switch was still depressed and light illuminated. I turned it off, turned the fan off and then turned it back on again. It began to work normally. This happened a few more times before I made it home and parked it. Also, for a few weeks now, I noticed that if you press the recirculate button, it takes some time an dthen the light will come on and you can tell it is in recirculate mode.

this happen to anyone else?

Your compressor clutch needs adjustment. Any good AC shop can do this and it does not require loss of R134a.

The slow to recirculate is just that the flapper needs to be used more, or oiled up. You could also check/replace your cabin filter, it should be dirty.

Thanks Klaus.

I did check the low pressure the other day with a manifold guage. At 90degrees ambient temp, it was pulling between 25-30psi. I added about 1/2lb of refrigerant. I have not had a problem with it since; however, either this is the beginning of a leaking evaporator or just natural loss through porous hoses etc of 9 yrs. Time will tell.
