Well i posted about my ELC not working a while back... anyways, long story short, i connected 12V directly to the compressor and it makes a sort of clicking sound. Almost like it is seized up or something. i tried tapping it lightly with a hammer, and no go.
My question is this: if the compressor doesn't work on 12V directly, is there still relays or fuses that could be preventing it from coming on? Or does this mean the unit itself is bad?

if you put 12v direct to compressor an it didn't run, it'* bad (with 1 caveat). the true sequence of comp startup includes a purge that reliefs pressure on the comp piston to allow it to start easier. but if yours hasn't been running, that situation would be non existent.
I call bad compressor.

alright, an update

I don't really want to spend the money on a new pump if the shocks are leaking (which i wouldn't doubt... the rear end is lower than the front)
is there a way to get some air into them without using the factory pump? If they don't hold air, i'm just going to ditch the ELC all together and get new shocks.. but i would like to find out which route to take, depending on whether they leak or not.

lift up the back end so the wheels are off the ground. if there is a whole in the strut bellows you should be able to feel it. Also when you let the car down fairly quickly, if there is a hole, you should hear it leaving the struts as it would have sucked air in when raised. there is no way to fill the struts externally. You could take the line off of the compressor, fashion an adapter, and fill with an air compressor.

i was able to ghetto-rig a system to get air into one of the lines with an air compressor, and it raised the shock up!
so now i know that at least one of them is good.
I have an idea, that i think should work, but post your thoughts.
I am going to find a T-connector the proper size for the lines, and splice the two pump lines into the line with the schrader valve on the inflator, and bypass the pump completely. That way i can fill them up with the scrader valve easily (evn at a gast station with free air for tires)

Ok....here is what I did when I totally took out my ELC.

In the trunk, there is going to be a solenoid that controls where the air flows from the ELC pump. One will go to the pump, one will go to the struts, and one goes to the fill valve in the trunk (where you put the air hose if you got the kit). I can't remember how I rigged it, but I ended up using the schrader valve in the trunk, and spliced in a connection to go from the end of the hose that the schrader is on, to the other hose where the struts get their air.

Still looks totally stock, and you still retain air function...just in manual fill form

that'* basically what i was trying to say, with one difference. i thought that the 3 lines were for Left shock, Right shock, and Inflator. are both shocks on the same line instead?

that is correct, both struts fill from a common line. that way they equalize automatically.

so what'* thte 3rd line for?

the air line from the compressor goes into the solenoid/switching assembly. From there it is routed to either the output valve in the trunk or out to the struts.

so to recap, 1 goes to the struts, 1 goes to the valve in the trunk, and 1 goes to the compressor
