I have an 07 gl450. My suspension was bad and we finally were able to change both front struts, compressor and valve block for it to finally work. The car has sat in the yard for about 2.5months and battery was dead. We finally get the car up and running but AC does not work, only blows hot air. We tried to add freon but it will not take. I took it to an AC shop where they evacuated and tried to add more freon and he said it will only take 1lb and rejected the rest, not sure what they meant. But i'm back at square one and this weather is too hot to ride around without AC. Has anyone had a similar issue and can you please advice what fixed yours?
