Heater blowing cold air until I get on the interstate, then it works; however, when I stop at lights it starts blowing cold air again. The temperature gauge will be in the middle but the car will still be cold until the car starts moving.
I have the similar problem with both my Jaguars, one is a 1988 Jaguar XJS, the other is a 1987 Jaguar XJ6, both blow COLD air out some vents while it blows warm air for heat. I heard it had something to do with the cold air blowing as a dehumidifier, I don't know if this is true, but it is really annoying to have both cold and warm air blowing when I need heat in these cold Canadian winters. If you find out please drop this website a note and let us know how you solved it. thanks.
Has the vehicle overheated recently, if not there is a failure of the Coolant from engine valve controller, that measures flow through the Heater Matrix. Come back with more, as necessary.

sounds like you have an air bubble trapped int he coolant system. Check coolant level in radiator and degas bottle. Make sure degas bottle cap is tight so it doesn't **** air in. This system is different than coolant overflow bottle.
