Hi, my car heater does not blow out hot air it only blows cold air all the 3 pumps are working perfectly all pipes a boiling but not going through the cabin thermostat is fine oil temp rewches btw 91-98, it was working quite fine 2 days ago but when i switched it to a/c to clear away fog then back to normal settings the hot air went away. The windscreen fets alot foggy. I was told its a heater matrix but the car is only a 2013 golf. I sprayed perfume/lynx in to the air vents but it dont know if that caused the problem. Is it the heater matrix need replaced
