How audible is the ACD Pump?

Guys

Its been a few years since I've done a clutch on an 05+ evo where I had to bleed the ACD system.

I just picked up an 05 and all 3 lights were on when I got it. Initially I tried bleeding it using the ignition, WOT (while off) method, and I couldnt hear any pump cycle. I know I have used that method in the past, I just dont remember actually hearing the pump.

Fluid just drips out of the bleeder, it doesnt come out with any kind of force....which leads me to believe its the pump thats gone....
