So I replaced the T-stat this past weekend. Ever since when my truck idles cold air blows out of the vents.
-ECT is near constant on 190 at 65mph or at idle. (+or- a couple degrees)
-Heat t-stat set on 90
-Doesn't matter if it defrost, dash, floor or combo.
-If the engine is under load the temp is fine.
-Back out of throttle and drift air gets cool.
-Stop at a light and it goes cold
-As soon as I take off and get a load on the engine it's back to hot.
-All ambient temperatures.
Any ideas what could be causing this or ways to fix?
