Anyone have a eatc vaccum solenoid assembly for referece?

Hello, I am a retarded guy that started to get ready to replace the orings in my eatc valves and dropped the valve manifold and lost the correct orientation of the valves and which solenoid went to which valve.

I was being lazy and did not mark them, so now i'm in pickle.

I was hoping that somene might have one lying around and could potentially take a pic or two or maybe even hit it with a meter to see which solenoid goes to which pin on the little connector...

I'll paypal someone some $$$ for their time if there are any takers...

Thanks guys!
 
I used my multimeter t find which solenoid connects to which pin. I matched each pin to its corresponding solenoid by measuring for zero ohms between the white wire at the connector and the white wire at the solenoid.

Hope this helps:
 
Man! That is awesome!

I appreciate it!

I hooked it all back up in the car, and I used the multimeter to make assumptions about which one was to be on and off with the different buttons selected. But this mapping will verify my assumptions!

Basically at least on the side for the recirc door and vents. It looks like the recir.door solenoid (white hose) has voltage when A/C is off, and for MAX A/C. Then the vent solenoid (blue hose) has voltage only when in "A/C", "Max A/C", and "Vent".

So this sounds right, as I read that the recirc door is open when the car is off, so it makes sense that the recirc door is opened when the A/C is off...

My O-rings by the way were crap, 2 still fit kinda snug, and 2 were loose as could be. All seemed to be shrunk and/or hardedned. So I ordered the new ones from mcmaster as identified in the eatc oring sticky.

I used a jumper hose to operate all of the vaccum actuators, so it appears that they all work. So I have to fix this, then it looks like I have to replace the dang blower speed controller...

My blower just started running constantly the other day. It blows with the A/C off, and it blows with the EATC head unit removed form the car. It seems to be blowing kinda medium, but if I put the blower control wheel on max it does seem to blow slightly heavier. Which confuses me. I would have assumed that if the relay was stuck, it would have stuck in the max position, and the wheel would have no effect. So it makes me wonder if there is another relay in the BMSC... I also swapped the blower motor relay in the power-d box with the air suspension relay, and it had no effect.
So my only option seems to be to replace the BMSC.

Any other ideas?


Thanks again GMMS!
