i am looking to replace my heater core i believe there is a leak in is somewhere my windshield gets foggy with the truck at full operating temp heat all the way on blower motor on high and defrost and the side windows get a lot of condensation on them so basically im driving like this :SHOCKED:. it takes a while for the heat to begin coming from the vents and it is not HOT its just kinda warm until its been running for a LONG time i have looked into a Chilton and it says i have to drain the A/C system and remove the lines! is this true and is there any EASIER way to do it or any helpful pointers so i can make this SEMI easy
thanks in advance
