Right, so the triangular light is illuminated when what happens? The solenoid is actuated? (assumption has to be made somewhere that this is the electrical signal generator, since there isn't a pressure sensor in the feed line?
The only bleed I found was on the side of the valve itself,the bleed bolt being just below and to the left of the solenoid ... is there another one on the top of the differential? (this is the valve assembly behind the fuel tank on the passenger side of the car)
Is it reasonable to just pull the entire ASD valve assembly, take it apart, make sure lines are draining with no blockages and that solenoid moves in response to 12v?
When I cracked the nuts on the lines there was some pressure, but not as much as I though there should have been, fluid poured out but didn't squirt (engine was running) ... this, combined with an early morning thought that I rebuilt the power steering pump in 2007 (has worked great since then) and perhaps I screwed something up since it also provides pressure to the ASD?
