Cold weather = Heater gone....
So just as the cold weather has started and my heater no longer works, just blows cold to luke warm air (then sometimes back to cold).
After starting the car (GT jtd) the engine will slowly warm up to 90 and stay around there (at least thats what is displayed) but the heater will stay just blowing cold, sometimes when i get onto the A road on the way home it gets hot after i have put my foot down for a while but today just stayed cold.
Any idea's what this could be? air temp sensor in car? thermostat problems?
