my compressor is not working . can anyone tell me how to jump the clucth to see If it is engaging . there is one wire coming off the compressor looks like it runs to the cooling fan.

 

You really need to do some testing - have a set of gauges to read high and low pressures....have a volt meter to do some other simple tests?

When you press the AC button and have the blower on - do BOTH cooling fans come on?
