What you described doesn't make sense. The clutch on the compressor is magnetic. However, it won't engage, most times it is due to no power to it. What needs done is to have a jumper wire (fused) that can provide 12 volts of power to the compressor clutch to see if engages, or simply, check to see if there is power to the compressor in the first place.
If you have a multi meter or volt meter, I can tell you how to check it yourself. As of it taking an entire day, it could if it is an electrical issue. However, by checking for power, you could eliminate a lot of questions.
Let me know.
