For the last few years we have had a problem with the Air Conditioning system working intermittently. It works fine in warm weather but it cuts in and out in hot conditions. This has become worse and is now unbearable forcing us to look at new cars. The system was checked out extensively by our Nissan dealer and the conclusion was a sticky valve/sensor somewhere – basically the tubes needed a clean out. Their solution a whole new AC system for 2800 euros. This includes a new compressor when obviously to us the compressor works fine.
