Hello people Have just a problem with the Volvo 940 of a known. (Bj 98 121 KW, Automatic, climate to 2 9101 to 3 763) For some time week after week about 200ml of water is missing in the balance tank often fog the windows in the interior and the floor in the driver’s footroom is wet… My suspicion was from the beginning heating cooler/heat exchanger. I tried to read several times in the forum what it might be about and found something with a valve above the pedals and stop the heater cooler /heat exchanger that is supposed to sit above the passenger footroom.. but there it is not wet.. I only saw driver’s footroom on the right that there was a drop of liquid hanging at the exit of the lower ventilation but was not sure if it is not possibly only water and since the side of the carpet was not wet I am not confused… Found the order very strange… Well maybe someone knows indeed guess.. Has someone possibly got an idea like the heat exchanger out of the whole mess or possibly pictures ???
