The only way the distributor would affect the idle and make the
car "vibrate" is if it is not set to the right timing. Vibrations are
usually caused by a failed or failing damper pully on the crank
shaft. You dash board has mini light bulbs in the back of the
instrument cluster. They can only be changed by removing the
entire cluster from the dash board and taking out and replacing
each bulb. Unless the bulb is completely black or you can see
the element inside it is broken, you will need to use a continuity
tester to check each bulb to see if it is good. I am not sure about
your model, but the 2000 has 3 different size bulbs inside the
cluster. As to the power surges when pushing the window
buttons, I would have the drive belts and the alturnator checked
because it sounds like you are not getting enough output when
you operate the accessories.
