Cadillac Repair: Electronic Level Control 1988 Fleetwood FWD, electronic level, vice grip

Question
My 1988 Fleetwood Air Pump will pressurize the rear struts just fine, but will not hold the pressure.  Is there a way to open it up to repair the leaking valve?  Now, I just pressurize the system and pinch off the line with a small vice grip and do it every few weeks.

I also have a 1994 ElDorado whose drivers window goes down but not up.  Makes noise and have to help window up where it stays OK.  It is just never used now.  Any thoughts? How to remove door panel WO damage to service (I assume) the regulator??

Thanks for any help you can render.

Answer
You would need to spray all the plastic air lines and the shocks with very very soapy water from a windex spray bottle to locate the air leak.

As to the door panel: You will need several pictures and this websit which is not mine only allows ONE picture, You will have to e-mail: onlineautohelp@msn.com
