The screeching sound is probably the drive belt slipping because it's loose or worn out. If it's been slipping it needs to be replaced anyway. The humming noise is a mystery, you haven't given me much to go on so I'll guess that the power steering fluid is low. I'd say that the window problem is due to a worn switch or motor in the door, or not uncommon, that the wiring in the doorjamb is fatigued and broken. Not related to the other complaints, I don't think. If you want to find a specialist, here's a directory link for you: https://repairpal.com/cadillac-repair-in-philadelphia-pennsylvania
