There is a leak or gap at the top of the windshield allowing water to get into the car. Most notable when there is a heavy rain and the car sits overnight. Then what happens is that the water that gets in either fills up in the interior dome light areas or splashes out onto the gear shifter creating puddles. This can be distracting while driving as water will splash on one's face from the water that is pooled in the dome light areas. Also there is a fear that this can cause further electrical damage, Some of the lights on the gear shifter are already not working as a result. This moisture has also begun to deteriorate areas of the instrument panel as well.
