I just noticed for the first time that the draw string on the BACK window shade is extremely frayed. This is not in an area that hits or rubs on anything, so I've no idea how it happened. My question is this, how hard is it to have that repaired/replaced? Is it a DEAR HUBBY job, or would we have to take it in...... and while we're at it, would that be covered under warranty? Can you tell our warranty runs out in three weeks!???
