Brrrrr! Chilly R33

[Greenwich-biker]

The A/C will not blow warm, even on the coldest morning, with control set at 31 deg. Please help, winter in Tassie not funny.

Tried searching, but not found exactly the answer I'm looking for.

I assume faulty sensor??

Help bbbrrrr...

Yep - engine reaches normal operating temp, 25 Km drive to work, still blowing cold.

Heater core blocked?

has it ever worked since you have owned the car? if yes then do the climate control diagnosis. if no then check to see if the heater box coolant lines are connected in the engine bay. it is common for the heater box to leak so people disconnect the lines. may also be that the heater tap is shagged.

On my r32 I had to hold the raise temp button till it overrides the climate control and says FH on the screen "full heat" before any warm air would come not sure if it works for r33s aswell

On R32's it's almost always the servo actuator that controls the door which controls whether cold or hot air comes in, the dry solder joints crack and the servo gets stuck in whatever last position it was when it was still working.
