My 1998 Camaro's AC compressor will not engage the fuses and relay are all good Any ideas?
This could be because you have a leak in you A/C system causing a loss of freon. When there is not enough freon in your system the A/C compressor will not engage, it will harm the compressor.

Ac compressor not coming on in a 1992 Buick?
Either low on freon or the low pressure switch is bad. You are gonna have to put a set of gauges on it. Usually this happens when the freon leaks out of the system. If there is not enough freon in the system, the low pressure switch keeps the compressor from coming on and being burned up.

You will have to figure out why: This the 90% of the time failur: Is there Freon in the system, if there is not a minimum pressure, usually 17 PSI, the compressor will not run. Is the compressor and clutch capable of working? Is the fuse in good shape.
