If you have ever worked on a Nova with air conditioning, then you know the pain associated with changing the #8 spark plug and removing the passenger side exhaust manifold. Usually, the compressor has already quit on these cars, and sometimes portions of the system have been removed.
At this point, you tell yourself that you don't need a/c, you've got windows. So the stripping begins. Good bye, condenser. Asta la vista compressor. Oh, look. There are a couple of extra brackets on the manifold and power steering pump. Chuck'em. That nasty heat exchanger in front of the radiator? Gone.
O.k. We're down to the box on the firewall. You've gotten rid of 30-50 lbs in the engine bay. But you still can't get to your spark plugs. That box has got to go. The easiest thing would be to get a heater only box and just swap them. But it can't be that simple. There's no way.
Question: What is the correct procedure for converting an a/c car to a non-a/c car? Does it require a different heater core and interior plenum, or just a simple firewall box swap? Are the blower motor and fan the same? Which wires can be removed? The options seem endless!
