I need someone to clarify this, but I believe the zetec was offered at one time or another w/o A/C, correct? If that is the case, you just need to remove the compressor, replace it with the non-A/C idler (if it has one) and the belt. The rest of the stuff, you just remove. If nothing else, this will lighten up the car's nose and help out cooling.
Keep us posted on what you find. If I move back home (north), mine's coming off....considering I only use it in Houston when the wife is in the car
