Hey everyone, got no love in the Truck forum so I'll ask here. Just want to know if the AC Compressor is the same on the 99 Frontier as it is on the 240sx or altimas. When I turn on my AC it makes a hell of a noise, louder than a regular belt squeal, so I figure the clutch on it is going out. My local junkyards never have any frontiers and but altimas are a plenty, sometimes s13.

You could check out the drawings in the FSMs and compare the pumps, or take detailed pictures of your compressor and compare them while at the junkyard.
