[2003C4S]

i own a 2003 C4S with 17K miles on it. a couple of weeks ago the air conditioner quit blowing air. Pretty sure it is the Air Blower behind the firewall. i have worked on a lot of cars including older model Porsche's but i have had the aid of a motor manual.

can anyone give me advice on where i can get some detail information about how to change the blower out? it shouldn't be to difficult, but in some of the forums there has been some suggestion of removing the gas tank. i don't want to start a project and get in over my head.

thanks for anyones help in advance!
