	On my daily a 2002 volvo v70 D5. So looking at jobs i can do while been confined to the house for atleast the next month. Air con has never worked for me, and i don't think for the previous owner - so say at least 3-4 years. Ive stuck a pressure gauge on it from when a bloke at work diy refilled his and it read zero pressure. I'm not really willing to spend alot on fixing it (due to it not working for so long) - so is there any diy tests i can do to find a potential leak with home tools - bike pump etc. Or should i just pay up for a test or live without it.

	Hi, The best and first thing to do is a visual inspection to see where it's leaked from. Because there's oil suspended in the refrigerant look for slightly oily dusty areas, the most common places are stones impacting the condenser, the rad in front of the water one, and around the front of the compressor. Also around any clips holding pipework. Don't go pressurising it with air because it's too humid and may cause more trouble than it cures. The gas the pro's use is OFN (Oxygen free Nitrogen) to pressure check while watching the gauges, after doing a vacuum test. Your inspection will give you an idea of work and likely cost of what may be required. Colin

	cheers for the reply, I'm going to get it looked/pressure tested by a garage when all this mayhem is over.
