    If you really want help, you're going to have to try a lot harder than that. Year, make and model are the bare minimum if you're serious about wanting help. Do you really expect people to post information for every year, make and model truck ever built? Or can we possible narrow this down to maybe just yours? The quality of the answers you get here will be totally dependent on the information you provide, which is this case is extremely poor.

    1999 4700 international DT466E AC comp not getting any power. The ac switch in the truck has power to it and when turned on has power coming from it,but does not get to the compressor.

    You need to get to the thermostat which is located at your evaporator . It is mounted to the side of the evaporator and has a probe going into it which shuts power to the compressor if it is freezing, or in your case ,Amy have gone bad.
