My 2009 blower didn't come on twice now in -20*F weather. Could this be the cause? After it warmed up in the shop it came on and works perfectly

It looks like the symptoms are different, but the dealer may be willing to try it. Print and give the bulletin to the dealer. They may not be aware of the bulletin yet.
