Hi all, 1997 Expedition 5.4 XLT My A/C is charged (i bought a can with a gauge and checked/recharged a bit) and it blows cold in the back but not the front. Occasionally in the past, heat would not come out of the vents (but they would still blow air) so after turning the temp knob back and forth, it would work. Last time it did that I could hear a single snap/click sound coming from the glove box area and then the heat would work. Sooooooo.....do you think it's the actuator or the blend door? I just bought a blend door today because thats my guess....but I just want more confirmation before I take the dash out that's the only way to replace the door is take the dash out right? Which one do you think is broke? Thanks!
