99 Expedition Climate Control Codes? 12 @ 49?

Hello everyone....just joined the group...just purchased a great 99 Eddie Baurer Expedition....runs great except that the heat won't blow...I got the diagnostic trouble codes and they are a 12 and 49 .

Does anyone know what these mean? I am visiting my Mother out of town and she has a dinasour for a computer so digging through the web is very tedious.

Any help you can give will be greatly appreciated.

Thank you,

Milkman

Sorry, can't help ya on the codes...But the simplest, most overlooked thing to check first is the coolant level. The first sign that it may be low is the loss of heating.....
