As title said,

My heater today started blowing only hot, no matter the position. Couple of days before was only warm on cold position, got warmer and warm and now only hot... I thought about HCV, but if i turn the A/C on, it gives cold :)

any idea? panel, or valve?
 
ok, thermostat changed, still overheating... cylinder head down, planned, removed 0.1... don't know if this is the problem... we will see... maybe a blocked radiator? lower hose is hot, higher hose is cold... coolant temp rising... maybe faulty temp sensor? i understood the puma has two sensors... one for the gauge, and one for the ecu... the gauge one is working, where is the other?

thanks
 
Does the fan come on?

My problem after replacing the HCV was the actual control panel near the gear stick.
