A/C compressor

[rlg]

Hello again.

AC clutch does not engage. Clutch engages with 12 volts direct. I do have the C68. Fuse is good. I tried jumping the Low pressure switch, did not work.
System has pressure and there are no codes thrown.

The FSM talked about a 5 amp under hood fuse, but if it's there it's the most hidden fuse on the planet.Reman ECM , I did all of the disconnect routine but still no voltage.


Any Ideas??

Thanks

While there may still be pressure in the system, if it isn't enough pressure, the clutch will not engage. You might have a small, slow leak.

Bay,

Pretty sure I have a small leak, all of these sytems had this issue.. Problem is I can't get the compresor to engage to load more freon.It's not getting 12 volts to the compressor. I tried jumping the low pressure switch and its not getting 12 volts .

think it might be the relay or the programmer
