Re: Just got a 96 CV with a few bugs, need help!
You have a laundry list of problems, but I will try to address those which I am familiar with. Taken one-at-a-time, they should be easy to fix.
Start with Cat's advice, but disconnect the battery first, then be careful removing the switch escutcheon plate on the door. The plastic tabs are easily broken. I usually gently pry them from the front. Sometimes spraying the switches with WD 40 is all it takes, but once removed, you can test the switches with an ohm meter and the problem should become obvious.
Your driver's side rear window most likely has a broken cable or plastic attachment point where the cable connects to the window. If broken, you will need a new window regulator. The problem will become evident when you remove the door panel, and replacement is straight forward. You will need a pop riveter, or alternately, use self locking hardware to replace the pop rivets you must drill out to make the repair.
This would also be a good time to check the child locks. I don't have much experience with these, but I did have the plastic tab brake on one and it caused the same symptom as yours. The door lock mechanism must be removed for the repair, but this is also an easy repair once you have diagnosed the problem.
It is normal to hear the motor run periodically in a properly running air spring system and there is no way to get your air ride to stay inflated unless the system is operating properly. Try turning the switch (in the trunk) off overnight, then turn it back on and see what happens. If the motor runs and the bags inflate, then the system is, at least, working. Next, check all electric connections for continuity. Don't forget to check the air spring valves and ride height sensor connections too.
Get back to us, let us know what you have found, and we can go from there.
