Im a newbie and if Im in the wrong place; Fine, cuss (at me)! tell me to leave; but at least tell me how to get to the answers and help I need!! I've replaced the comp. the accumulator the orifice and flushed the system! I vacuumed the system to 30hg for 1 hour, I charged the system and it worked fine for one week! now the comp clutch will not engage even though the system is still fully charged and the fuses and relays are fine, and the pressure switch has been replaced? The cond fan comes on as soon as you cut the ac on but the comp clutch will not engage? (ECM)??

 

Is there power at the compresssor?

 

none!
