[QUOTE="Tree Trimmer, post: 1435340, member: 716"] as a side note. don't these trucks have a contraption somewhere in the heater line to block/shut off the heater hoses when the air conditioning is on full? i installed one in my 99, out of a 07 i think. was just a vacuum operated shut off valve. when the air was on max, the truck operated a vacuum blend door in the dash to go from fresh air to recirc, so you tap into that vacuum line and when it shut that blend door, it also shut the heater hose off. maybe yours is stuck shut, if your truck has one.
