So, my boss is giving me her 850 turbo wagon for helping her do some work at her house. She told me though that the wintermode light would come on every now and then, at times when it shouldnt, and she doesnt know whats wrong. I checked the codes but only got a 1-1-4, 2-2-3, and a 3-1-3.. all ac related... so what could be wrong?????? Thanks.
