I had my compressor rebuilt, and all under the hood checked for leaks. Checks good. However, the Freon doesn't last more than 45 days, then warm air is what I get. The air conditioner was not used by the previous owner (for 12 + years!), so I believe there are other check/replacement points that must be looked at in the trunk unit. Can anyone please help with what should be done to correct the situation? Should anything be replaced back there? I am no mechanic!!! So please tell me specifically what should be done and/or where I can find the instructions/parts, etc. Thanks, VERY MUCH, for your help. Tony
