Sounds like u have a bad window regulator which is a system of channels and guide wires that move the window up & down. since i do not know the whole situation I would make sure the window channels are lubricated with silicone spray to make sure the window is not being held up on anything.

Ok, trust me on this one, take the drivers side tire off and remove the forward inner fender panel. If you try it without removing the tire, it is just a royal pain.

SOURCE: how I take the battery off my car?2008 Dodge

On a Dodge Avenger from 2008 the battery is behind the driver side wheel. You have to take the wheel off and then remove the plastic fender and the battery is right there just behind the front light. Here's how to replace it: 1. Block your tires, jack up the left side of your car and place a jack stand under your car. Luckily for me I was at home and had access to my stand. If out and about you may not have access to a stand, make sure your jack is in tip top shape.
2. Remove your tire. You possibly could do it without removing the tire, but you would be making your life so much more difficult. 3. Now you have accessed the wheel well and must remove the fender shield. There are two socket head bolts on the outside which are 9/32." Next remove seven push-in style retainers. You must pry them out carefully so that you can reuse them. 4. You can now for the first time see your battery, but you are not quite there yet. There are two retaining systems in place. First is a cross way bar which is removed using the 13MM Socket. Next you must remove the actual battery restraint. This is held on with another bolt that is also 13MM. 5. Remove the battery cables using the 10mm socket. The red cable comes of fairly easy, but the black cable is a bit of a stretch. If you have short arms you may need some help here. Also I could not get the socket onto the black cable, so I needed to use the open ended wrench. 6. Finally you battery is free. Pull it out carefully and place it aside. Now slide in your new battery. 7. Inspect your cables. Make sure that everything is in good shape and that you have a solid connection before you put everything back into place. 8. Replace everything in reverse order.
