Hi there,

I've just bought a secondhand 2000 Mazda 626 Lx in very good
condition except for one odd problem: when I try to select the
Defroster Air Flow mode (air towards the windshield) the air
conditioner starts working by it-self, even if the it's switch is
off.

Any suggestion?

Best regards.

Ah, I'll bet that it's a feature, not a bug. Cooling the air has the
side effect of dehumidifying it, and some manufacturers switch on AC
whenever defrost mode is selected. Not too helpful on a 12-degree
morning when the engine is just starting to warm up...

Sounds normal. Most vehicles run the A/C in Defrost mode.
