The AC in my cutlass has been an issue for a while. We replaced the compressor, blower motor, etc, etc. but I keep having issues with it not working ever so often. Usually when it cuts off I check the "AC" 25 Watt fuse and the fuse is melted but not severed. So today I replaced the fuse and it worked for a couple minutes and shut off again. The fuse looks fine but the AC will not come on at all anymore. We've replaced the relay switch on the dash a few times and it will work for a while then start having the same problem. Here's some photos, it's a bit of a mess. We put in a rebuilt motor with an Edelbrock carb so all the electronics are disconnected and just laying around. Any ideas what would cause this?
