My 2005 Outback hasn't had heat on the driver side for a while, so I finally decided to get it fixed. At the shop, they tell me that the part is now discontinued. The part number is "72131AG12A". I've looked through about 10 different parts websites and have not found a single one available. Does anybody have one or know where I can get one? It's pretty cold in Idaho and I really don't want to have below zero temperatures with my Air Conditioning on.
