It seems the A/C in my 99 Sintra is not working :( chap just came around to check the gas and that was fine, fuse seemed ok and as far as we could tell the diode thingy was working. He did notice that the relay was not clicking. The light comes on on the button and I hear a small click when I press the button but no cold air. Any ideas or is this a vauxhall garage jobbie? Cheers, Chris.
