only heat whern press gas
 

the title say it all i only get heat when i press gas above 60-70 km/h what that mean ? vacuum leak ?

oh and i also get a check coolant warning light

Often means coolant is low or the system needs to be bled.

The heater gets its heat from the engine cooling system. If the cooling system is low on fluid, or has an airlock, it would be expected that you wouldn't get heat in the passenger compartment.

Plugged core, leaking coolant...start with topping it off, run the heat on full, bro the system and go from there...

dam im fucked again

Failed heater control valve possibly? If the seals fail often they clog up preventing coolant flow. Or they fail open and you have hot coolant going through the core at all times... seen both happen.

Not necessarily screwed yet. Please verify that you have checked coolant level and bled the system.

:iagree:

What do you know to bring you to that conclusion?

i bring the car to the dealer
