It seems to me that the bypass for my heater matrix is not stopping the coolant from getting through and I end up with a roasting heater when I want some cold air coming in to cool the footwell. The valve seems all the way closed with the cable all the way in. Is there a better way of doing this? Not looking forward to getting incinerated again.
Do I drop out the coolant and put a hose from the top to the bottom and live without a heater for a couple of months?
