1995 Lincoln Mark VIII 1995 Lincoln Air Suspension

I am not sure what the problem is, my front end does not drop like its supposed to when it is parked and between 65-70 mph the check air ride warning shows on my message center and then my rear suspension pounds loud, not absorbing bumps in the road. My door ajar sensor stays on but my interior lights go out, heard this can cause the air ride not to function properly, what seems to be the problem?
