Here's the problem. 1998 V70 non-turbo with manual (non climate control) air-conditioning . When out driving on warmer (90+ F), the air conditioner randomly cuts out after the first few minutes. It might come back on in a couple of minutes or in five minutes. (Yes I did read the other recent posts on this...no real information.)

Here's what I have checked.

--1. The diagnostic codes read 1-1-1 (everything OK) even after a reset.

--2. The drain tubes seem to be working (drip...drip...drip) no stink and
no icing problem.

--3. Low-side pressure. (That's all I can check on this car, right?) First, I run blower at top-speed and air on lowest temp for about 10 minute. Then, I turn the blower down to low and shove a thermometer into passenger air vent for another 10 minutes. It reads about 42 deg F. The compressor is cycling about every 15 seconds (ambient temp around 86 deg F). The low side pressure is 25 with clutch disengaged and tops at 50 while engaged.

--4. The pollen filter is about eight months old (and should be changed around here), but I don't think this is the problem.

--5. There is a service recall on the MCC controls for my year which includes my chasis number in possible replacements. (I think it was Service advisory 83A.) This might be it, but I' still vague about what the symptoms.

Any guesses would be greatly appreciated. If I can't figure anything else to try, I will bring back in, but only as a last resort. While the car was under warranty, I brought it in twice for the same problem and was told on the second visit, "Well the new R134a just doesn't cool as well as the old R12 and you'll just have to get used to it." (In other word, they did nothing.)

If anyone tells me that I should bring it right in to qualified Volvo technician, I will put his/her email address on a 1000 spam lists (Believe me. it's not that hard...)

Thanks in advance,

Optimist
