A/C and clicking noise V70-XC70 1998



Does anybody notice a click-click noise under the hood when the A/C is running? Dealer service rep said it's normal.

    You are probably low on refrigerant. Leaks can occur in the evaporator (dreaded), but also in the hoses. Mine had a leak in the hose that goes along the bottm of the radiator area. If it looks oily, that's your problem.

    Well, if you had an 850 I would say it's the compressor cycling on and off, the tick-tick sound coming from a relay behind the glovebox. But I'm not sure that applies to your car. It's usually indicative of the car being low on refrigerant (the dreaded 850 evap leak issue), although I'm in the process of replacing the relay because I am not low on refrigerant and I am determined to get to the bottom of my own tick-tock issues.

    But you could have your refrigerant level checked, that's a good place to start.

      My S70 clicks too, but blows very cold air. I have mentioned it to my dealer and they say it's normal. Others on here report the same.

        KC, Mine has done this since day oe. Like yours, my AC is VERY cold even on the hottest of days (in NYC). If it starts to blow air that is not as cold as I think it should be....it stays this way!
