a/c clutch won't engage

Clutch on the a/c compressor not engaging. Fuse is good. What is the wiring at the clutch and what voltages should I be reading? Thanks in advance.

There are many things that will prevent an A/C clutch from energizing. Low freon is the most common. You need to put a set of gauges on it to start with to determine if you even have enough freon to kick the system on. After that you'll need a schematic to determine the wiring configuration for that vehicle since they all differ. Switches or relays are common problems also.
