You don't need to remove the dash. Look under the dash where the switch is located. on the side of the switch you will see a small button to push in. While pushing in on the button pull the knob as though you were going to turn the lights on. At this time the stem should release from the switch. Undo the bezel and drop the switch down so you can see to unplug the wires. Replace wires to new switch and reverse the procedure to install. You don't need to push the button in when replacing the stem.

You will likely have to remove the panel from the inside with the window up. Once you have the panel off I would try to have some one hold down on the switch while you tap the motor with a hammer. Of course make sure the latches are all the way closed as if the door is not closed all the way the window will not roll down as it has safety switches to keep this from happening.

If you still can not get it down then you will need to unbolt the regulator and let it down that way.

The electric key switch is next to the key cylinder on the rear door. You can see it easily with the window down and weatherstripping pulled out. The wiring may have become chaffed with the window over the years or the switch corroded in the contact points inside.
