Power doors and hatch stopped working

2005 Saturn Relay minivan:

I'm not sure the order in which things happened because my husband was the first to experience issues.

The power sliding doors will only open manually, but they will close by pushing the interior button. The locks no longer work, so we do them manually. He believes a fuse blew because the hatch (rear) door is now stuck in the locked position and cannot be opened from the outside.

Help! Any chance we can fix this at home? Does it sound fuse related?
