Thanks for any input..KYVOLVO Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.

On Volvospeed some people had success cutting the sensor line but not 100% success and that sensor is there to protect from damage. This is about the 850 but the same applies to other models: http://volvospeed.com/vs_forum/index.php/topic/80181-850-ac-clutch-gap-fix/ My 98 S70 had the same problem - seemed to happen more when the car was hot (heat waves, stuck in traffic, just when you need it the most!) It seems to me this is a better fix because it is the root of the problem not a bypass. I tried it first with some washers cut a section out, did not use adhesive. My AC compressor was on all the time (even when turned off) because the washers were too thick. Luckily they came out after a few weeks anyway. So I re-did it with a cut up credit card, superglued in place this time. Bread ties did not work for me they kept breaking.

I had the same sort of issue. Next time it happens pop the hood and see if the AC lines (back by the fire wall) are frozen, if they are that's the problem. The sensor is located inside the car. What I think happened is the system froze and cut out. Then you shut it off and the system thawed, then you turned it on after it thawed and it worked. There is a posting about that somewhere on brickboard from about 2 years ago. This is where I found out about the fix! Maybe you can find it by using a search from my username. It's a real easy fix! -- 1999 S80 T6, sold my other two Volvos, Great Cars!!! Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.

Check your temp gauge on the dash next time. The compressor got too hot and shut itself down. Some folks have bypassed the compressor temp sensor. The fan relay for the engine is not working at high speed, just low.

That is very nice. It is supposed to cycle like that. When the clutch gap gets too large, it will no longer engage the clutch. Rust color is also normal. Klaus -- The more I learn, the more I forget.

If it's greater than .025" the clutch won't engage when the ambient temperature gets in the 90's. It will only get worse. The proper way to fix it is to remove the clutch faceplate and remove shims until the gap is around 0.015". Plastic or metal shims can be inserted in the clutch plate to close the gap but I think that's only a temporary fix. Search for instructions on AC clutch fix.

Try it some time in your driveway: with the engine hot and the AC no longer working, spray hose water through the passenger side of the condenser/radiator and I bet the AC clutch will engage. The engine fan MUST turn on when the AC is on. If not, check your fan relay. Klaus -- The more I learn, the more I forget. So why learn?

Turning on the AC must also turn on the engine fan at the same time, everytime. Because you have a lot of bugs down there, try flushing out the fins on the radiator and condenser with a garden hose. Right through the grill at "high" pressure, but don't use a pressure washer. You will be amazed at what comes out! Klaus -- The more I learn, the more I forget. So why learn?
