2004 Toyota Sienna wipers, windshield & visibility problems

Since 9/07, rear power tailgate would not raise to full height. Actually walked into gate due to this problem. Thought it was the cooler weather. As winter approached, the gate would raise, not fully, then close on it's own, no warning. Without the power hatch, you could lift and hold the gate, but, it would not stay up on it's own. Toyota, can replace the gas struts/shocks, parts only $286/each.

While driving on the freeway the glass sunroof/moonroof of my 2004 toyota sienna XLE shattered. From the pattern of the glass breakage it looks like the glass broke due to interior cabin pressure. This is actually the second time this has occurred with this vehicle. We had been on the road for about 4 hours, we did not hit a pothole and we had not gone under an overpass. We heard a loud boom and then the sound of broken glass on the roof and dropping onto the sunshade.
