okay.. stupid question first... WHY???
second..
You can tell the car that it doesn't have climate control IIRC.. but that would also mean that automatic vent control, air recirc and temp control wouldn't also work.
There are market specific GTIs (e.g. for eastern europe) that IIRC dont have climate control as standard, but also of course, I'm sure that a regular 1.6 FSI Golf doesn't come with climate control as standard either.
