Leaky sliding glass door
The top of my sliding glass door is leaking into the house. The drywall along the edge of the top of the door is rotted. The exterior wall has previously had repairs because the deck wasn't flashed to the house properly causing severe water damage to the wall and foundation. Could this be the same problem? The roof has a steep incline without gutters and there is an ice buildup. Any thoughts?

It definetly sound like it could be related.
Water in the wall can be trapped by the header over the door and cause the sheet rock to deteriorate. I suspect there may be damage to the header and other framing adjacent to it.
When you remove the sheet rock to patch it, poke around with a screwdriver to see if any of the wood is soft or has deteriorated.

The patio door likely has a nailing flange on the sides and top. The nailing flange on top of the patio door, especially, should be sealed to the sheathing with a peel and stick membrane such as Grace Vycor Plus. The building paper should then overlap this membrane. As long as no water gets behind your building paper, your door should never leak on top. If water is getting behind your building paper, you've got big problems and need to find the source.
As you mentioned, the deck ledger is definately the most likely source of the problem. Deck ledgers need a flashing below (behind the building paper and ledger, then over the siding) AND above (behind the building paper and siding, then over the ledger). Failure to do so will cause the sheathing to rot, will likely cause the ledger to fail, and water will pour into the wall every time it rains.

jreschke,
You've got a nitemare that found a place to happen!!
Your's is a perfect example of why I DO NOT ledger a deck to the wall. That is just a leak waiting to happen because they don't get (or, in some cases CAN'T BE) sealed properly.
The cure is to start with the deck and eliminate the ledger. Make the deck free standing. Then seal the exterior wall. Now your incoming water problems will cease, but you've got to repair/replace all of the water damaged framing and sheetrock.
