Hi

today my car don't want to heat untill i depress the "defrost switch".So with the switch on it heats full witout problem.The temperature knob doesn't make any differnce from cold to hot.
Before it works you can heard an audible "click" when it goes from cold to hot and viceversa.Now nothing.

So it blow cold all the time untill i depress the defrost switch.It works fine for years so is a new problem.
Water level ok,heathing valve ok,clip ok...

Any ideas?
Thanks
