My friend has a 72 GS and he wants to remove the A/C. We are pulling the engine to clean it up and while it's out we were going to replace oil pan gasket and do some other stuff. One of those other stuff things is removing the A/C to open things up a bit under the hood. We are in Maine anyway and don't need it. Couple questions. What needs to be done to make it completely a non-air car, functionally, with heat etc, since we are taking A/C out. Will the existing blower motor amd heater core work? If not, no problem, I actually have 1 of each and can install them. The delete plate they make to cover the firewall opening that will be left, does it incorporate the proper bulge for the blower motor to make it look like a stock non air car? What other stuff to consider? Fuses, relays etc.? Thanks, Ken
If you get the aftermarket A/C delete box, it will work and replace the AC cover outside. Your blower motor goes in it, just like it does the current one. Only thing you have to do is put the blower relay in the box somewhere. I cut a hole in mine and installed it. The firewall is different between AC and non AC cars, so you can't use a stock original non AC box on an AC car.
Another option,. Im in the process of the same thing on one of my cars I took an extra ac box trimmed off the unnecessary material and glassing it all back up , cheaper , quicker and a better quality part in the end as the aftermarket covers are prone to cracking at the mounting points and take 3 to 4 weeks to get
Hugger, you have any pics of yours from beginning to end? Or at least the finished installed product so I can get an idea? Also, when you used your original box and glassed it over, you just glassed over the A/C line holes? Is that all you have to do? The after market box is basically the same as an original box without the holes in it? If so, that sure does seem like the way to go doesn't it?
I think that relay is just below the ac lines in your current box. You use the same relay in that aftermarket cover, but you have to cut out the hole for it. I used that acdelete box on the red car. I took forever for them to ship and I actually found one on ebay before they shipped it. That was several years ago. The box has been fine, no issues at all with it. T There was a thread on V8 that had pictures where somebody just cut up their AC box and glassed it over to make their own.
Can someone tell me what these parts are called and whether they can all be removed if deleting A/C? It's a 72 Skylark. Never deleted A/C; this is my friend's 72. He ordered a delete plate. I assume all this mess is coming off obviously, but I don't know what any of the parts or wires attached to this do or how disconnecting them will affect anything else. I assume different controls for the heater now? what else needs to come out or get replaced when deleting A/C? Sure this has been done by somebody on here?
I've never deleted an a/c, but I can tell you that the big plastic can looking think in the first pic is a vacuum reservoir for the hvac system - if you get rid of it you'll need another way to control the air doors in the heater / defroster. The whole assembly in the second pic is the a/c evaporator, it all unbolts from the firewall. One thing - that big funky-looking piece in the top hose is a POA valve, and it's worth either selling or saving - they're getting hard/expensive to get.
Here is my factory a/c car that I cut up the old box and fiberglassed over. This picture is 4 years old and it is holding up ok so far.
