Question
Hi,when i switch heating on there is no warm air,and there is only a little air when i switch on the blower,freezeing dave.

Answer
Is it a fan issue or heat issue?No heat means the coolant is not flowing through the heater core and could possibly be a blocked thermostat or other coolant issues.No fan could be a bad resistor on the fan or electrical problem in the controls.The same goes for the heat change over valve under the hood,(bonnet).
