Hi guys, I expect this to probably be a reoccurring theme, however my car is frozen! I am constantly filling up my heater reservoir, and I just dont know where the water is going, I cant find any leaks, and then the heater only blows cold VERY cold air around the cabin, I think it was warmer outside the car then inside this morning!! Now could this be my heater matrix, I know the reostat only works on high speed but I cant see this being the problem, Any ideas, suggestions on where what to look at? A rough price to fix, and maybe if it is the heater matrix, whats the cost?? Cheers,
