Apologies if this sounds a silly question but I have no idea regarding air Conditioning. I have just bought a Vectra that has a seized engine the car has been fitted with air con. I plan to fit a replacement engine in next weekend. To give me more room in the engine bay I want to disconnect and remove the air con pump. There are two pipes that run to the air con, my question is this: Can I just disconnect the two rubber pipes? I am not worried about the air con working afterwards as it's something I would never need. I just need to know that I'm not doing anything dangerous by disconnecting the pipes.
