My zafira is blowing out cold air , just wondering if it could have anything to do with water which I put into the car, the car temperture gauge on the dash board gets high after about a week so I keep the water topped up every week, if not car over heats,
Thanks you are spt on , when I fill up with water the heater works great, so must be a leak, so now do I check pavement where car is parked to se any wet spotsThe hot water from your engine is used to heat the car via a small radiator or heater matrix. If the water isn't getting to that or it is leaking then that may be causing your problems. Check any pipes in the engine for leakage.
