I cant seem to find one on Ebay. I need to replace a part for the AC. I cant find a shop in my area that will do it. They says its too complicated to get to. I ordered the part and my cousin will put it in but he needs a service manual.
Its the compressor hose

I have a 95 Aurora and I got mine at books4cars.com. It did cost $100 though. But I think this is the same book as the GM dealers use.
