It's there so you have some more defrost than you'd otherwise have. I just went through inspection today and had enough defrost with no blower, sitting at idle to pass. Any non-Porsche person who rides in my car is very cold weather can't believe it when I tell them I took the heater out. Same with my 993. Air-cooled cars heat just fine with just the heat exchangers.
