The timer thing only blows air (most likely cold) from the outside.
Tried it to warm car up and but all it does is circulates the air for hot climates?

On the other hand, the 'REST' button suppose to use residual heat from the engine to keep the inside warm when the engine is off.

But still that defrost features works magic.
