When I first bough my truck the passenger side vents only blew out cold air. After taking out the passenger actuator, I replaced it but had issues with the new actuator responding to commands from a tech2. Upon removal I tried manually moving the blend door back and forth but can only get it to blow cold. I am wondering if the blend door actually broke, it seems likely but I found it hard to believe. When I move it it feels like the door is attached I guess but it would be easier to figure this out if someone had a picture of what the door looks like in the heater box. Anyone got one?
