heater wont blow cold

[Aj1981]

Dosnt mater where i set the heater knob my vents only blow hot air out, any ideas guys? I'm having to drive with the windows or sunroof open as its cooking me.

It's propably the heater valve broken or the cable has snaped...

Pop off the plenuim? chamber cover (cover between battery and fuse box) Get sombody to operate the heater slider in the car. Where the heater matrix is, there should be a blue tube coming out of the bulkhead. This will have a Wire/rod coming out of it and onto the heater valve. This works simular to a throttle cable sort of thing. Im guessing either the gay little clip has come off that fixes the rod to to valve. But could be a snapped rod, broken valve, or somthing amiss with the internal control side.

Could be just a simple as the current ambient temperature.

Thermostat?

Mines always been like this, maybe its because G40 engines get stupidly hot?  I just open the window.
