I have a ´72 bb that was rebuilt in 2003. At that time the owner left out the AC on the engine but all other ac hardware is still in the car, taking up huge place in my engine bay. To simplify things I want to remove all the parts belonging to the AC as here in Iceland there is little or no need for AC anyway but I need the heat blower to stay in place. The space is very tight around the heat blower and Im wondering if anybody has done some write up of the removal of those left over ac parts. I know I need a AC delete plate or in my case I will build it my self. As well, is there something I need to be careful with?
Thanks in advance
They came with just a heater /Fresh air option as well , so if you source a non a/c cover it will take up less room . Or if your handy with glassing you could just modify what you have.
You can pull the evaporator housingm etc iyt if the vehicle to give you some more room in the engine compartment; but messing with the stuff under the dash would be a BIG MISTAKE and a real 'can 'o worms', IMO. The heater system with your present vehicle should work just fine, as-is. Not sure why you want to go to the trouble of removing that stuff. Just realize that, once you remove it, it would be a nightmare to re-install if a future buyer would want a working A/C system..
Believe you me that nobody in Iceland is expecting a AC in a antic car like this :-) Just open the window and the temp drops down to subzero. But the heater does not work and this is just a part of my process to simplify the electric system, remake it and get rid of things that will not be used in the car in the future in the place it is.

Your heater may not work because the [vacuum operated] water shut-off valve may be frozen in the OFF position. You should diagnose the actual cause of "no heat" before ripping out stuff that may cause further problems. (ie, all the damper doors that direct airflow to various outlets, etc) BTW, if you have cold weather, don't you need working defroster? If temp is above freezing, the A/C system does a much better job of defrosting than simply heating the windshield. I understand that you don't need "cooling"; but the A/C system can still be useful. And just removing it may not solve your "no heat" problem, either.

Remove the splash panel underneath below the side grill, then remove the side grill, careful (apply a lubricant to help loosen any fasteners, sparingly of course) this will give you access under the car. Here are a few pictures: Btw, Love your country, cars shows at the hall and Black Church.
Take pictures of everything you do. Think it through, it can be done. Attended a car show at the Hall Side Grill & Splash guard opening
1972 corvettes did not have a factory hot water shut off valve.
I used a a/c block off plate on my 71 when I was rebuilding the car as I knew I was going to Vintage Air. It worked great and the heat was great. We only got down to 10 degrees here .
The plate can be made or purchased for $50 , if you shop or $100 to $150 from many venders. Locating the resistor is important and you can see it in my pictures. It's a clean install and looks great. You can see the factory heater core on the bottom when installed . It's the factory A/C heater core. Be sure the trap doors move, the selector door is cable operated.
Thanks 7T1vette for your response. All you say is true and I should figure out the problem before I tear everything a part BUT what I actually am aiming for is movement of fresh air, no heat or no cold. The average temp here during summer is 13°C(55F) to 20°C(70) so there is actually not need for heater nor AC, just fresh air. The BB makes sure that I do not need heater anyway :-)
I hope you enjoyed your stay in Iceland :-) and maybe we have met without knowing it at Harpan where the carpicture is taken. Thanks for great pictures, some of them I have not seen be for and was looking for. In my case, the things that are missing in my car to day are at least,
1) Retainer to Fender skirt
2) Condenser inlet hose
3) Condenser and the condenser bracket
4) Receiver dryer.
So by the parts Im missing in the AC the easiest way to go is to clear the rest out of the engine bay and those pictures help me realize what needs to go and what should stay.
I will make my own plate as the shipping cost and taxes make sure that a thing I buy in us i.e delete plate that costs 150 usd in the US will cost me 150 USD + 150 USD shipping and in the end the total cost will be 373 USD. That is why I try do things the easy way instead of buying expensive parts for abroad.
You can add a hot water shut off valve, either manual from the local hardware store (I would recommend a SS ball valve) or a vacuum operated and just T into a vacuum line on the motor - plug in the vacuum when you want no heat and unplug when you want heat.
Once you pull the engine side A/C box off you will see the temperature control door, Make sure it moves - sometimes the cable from the control is broken or rusted.
If you use a hot water shut off - you don't need the flap to work as well. The cars were designed to always have air flow from the outside to stop carbon- monoxide poisoning.

Did you by chance ever work as a tour guide on a bus in the last few years ?
caskiguy funny you should say that, I actually went one tour as a guide 2 years ago but that is my only income into the tourist business ever.
Well Sveinn, it is a small world after all. My wife and I were in the front row behind the driver and I ( I think you had a mustache ? ) believe it was your first time as a guide, you did great.
How crazy is that ?
Best of luck with the Corvette, post pictures when you can.

So to day I started and got everything out of the engine bay. It took time and some thinking as this area is totally full of stuff in a engine bay with big block. There is literally no extra room for the box to come out. Had to strip everything before removing the box, taking the box apart witch was the key thing in this work. Here are some pictures of before and after en one during.
