Airmatic Help Needed

I have noticed that if my car sits for a week or so, the car will lower to the ground evenly.
Now today the rear passenger side of the car had dropped to ground causing the rest of the car to be slightly lower, but this was the lowest point of the car.
Pump runs and builds the car up, do you think this a distrbution block problem?
I want to replace it and the pump to be on the safe side, I have already changed the relay.

I have also noticed on start up the pump has to run atleast 30 seconds every time.

You would be better off to troubleshoot the entire system; spray soapy water on the connectors and lines in your system; see if there is bubbling.

Your problem could be the distribution block, but it could also be a leak in a strut, or in a fitting. If so, you'd be replacing the pump unnecessarily.

My guess is the valve block, but bad struts could be the culprit.

Already replaced the front seals on the shocks and sprayed them to check no leaks there. It is looking like the dist. block. Are they all the same from 00-06?
