Owners/service Manual problems of the 2002 Jeep Liberty

I keep my car parked in an enclosed garage when it is not being driven. One morning, I went into the garage to drive my car to work. I used my remote to open my car door. I then noticed that the backseat passenger window, immediately behind the driver side was rolled down. I know I had not rolled it down. I got in the car and pushed on the button to raise the window. The window rattled and groaned with an electrical sound. I looked at the window - it had not rolled up. I had to get to work, so I drove my car with the window in that shape. When I got to work I asked a CO-worker to help me tape it up. So then, my window was manually pushed up by two people trying to push it up from the inside and the outside. Then tape was applied to the window to hold it up, but it started to slip down. So the person who was first helping put a piece of cardboard on the inside part of the window, saying that would prevent it from falling down. It worked for awhile, but then the cardboard slipped down into the window. So then, I found two bigger pieces of cardboard to hold it in the closed position and we taped some more. It is now taped up and so far is holding, but as rain may come, it will probably fall again. I called Jeep and asked how this could be repaired. They told me it would cost about $400. I don't have a spare $400 to spend on a car that has had a massive number of problems and has cost me thousands of dollars in repairs over the year. Then the next thing that happened was that the front driver-side hubcab disappeared - this is never ending trouble with this car. The car has been a problem from the beginning. I told Jeep early on - they would do nothing to help or exchange it for a car without problems. This vehicle is terrible, and the dealership is even worse.
