The easiest way to force the AC clutch to engage is to bypass the relay. A paperclip will work just nicely! What are the static pressures on the high and low side of ur AC?
As it was said here before if the refrigerant pressure is too low the clutch will not cycle.
Also u do not need to listen if it kicks in or not u can actually see if it engaged as the front plate of the pulley on the AC compressor will turn when it is engaged.

Do you know if pump has the under pressure cut out built in, or is it in one of the lines? All I have L3/I4 schematics and I couldn't find it.

Tks!

Anyone get anything figured out? I recently discovered that my compressor is not kicking on. The relay is fine, and I want to check the power going to the compressor, but I don't see the same wiring harness that flipper posted a picture of on my 2007 6i. anyone know where it is located on a 2007?

from all the reading I've done, It seems to either be my clutch or low refrigerant.

Mine turned out to be no refrigerant left. The o-ring by the fitting at the compressor was not sealing properly. I found that out by using one of the r-134a canisters with the gauge attached which also comes with green sealant to supposedly seal any leaks. The green stuff was leaking out the lower fitting. Got another o-ring from the dealer and was good to go.

Mine ended up being the AC control head.. The signal from the pcb up by the radio wasnt sending proper signal to turn on the compressor. I found a whole used head unit out of a totaled car on ebay for $95 shipped and swapped my custom radio stuff onto it and it worked!

Thank god it wasnt too bad..
