[QUOTE="duddy, post: 911379, member: 4714"] The only thing that lead me away from the hvac itself was the relation to coolant temp. It is completely predictable, down to a degree or 2. That is why I was thinking tstats sticking. But I have not been able to come up with reasonable reason to prove it to myself. I have a set that is going to be put in this weekend if I can not find anything, to cold outside to have no heat. [/QUOTE]
