i have a 98' s70. the ac worked when i initially turn the car on and would run for a while then blow warm air. also if i turn it off when it was working, and turn back on, it didnt work. i needed to wait 10 minutes or so and then it would work again. the fans work fine. to make things worse. i tried to fix it and unplugged one of the sensors in the line and shorted it out somehow. i cant find a fuse for it in the fuse box, and tried replacing the ac relay fuse. it doesnt work at all now! when it did work it ran fine and you could hear the clicking as you should, when it ws working and when it wasnt before i tried to fix it. now i dont hear anything and assume there is a fuse somewhere i just cant find. any thoughts would be appreciated, thanks
