Hi!
This is really useful stuff, everyone.
I recently had a headlight go out in my 2014 159"wb gas promaster with 190k miles. I replaced the headlight, then was told i had license plate lights out. Need to replace those, too. Thought maybe a surge caused it.
Today im noticing my heat isnt working. These issues all occurred within a week of one-another, and I am convinced they all happened at once. No idea what caused all three issues at once.
Anyways, I popped open my dash as discussed in
the post about how to "jiggle" the blend door and found my blend door.
I tried running the van, then flicking on and off the heat, as well as changing most of the AC/ heat controls and never once saw this blend door move. I felt heat in the pipes (be careful, this gets reallllly hot).
I am assuming that since i never saw this thing move, that I have either an actuator or blend door issue, though I'm still unsure.
I'm curious if anyone can answer a few questions.
1. How does this blend door move? I was not able to make it budge with my fingers at all, and definitely put some decent force on it in all directions. Does it rotate as it would appear to?
2. Does anyone have any theories what would cause all of my issues at once?
3. Should I still get cool air + ability to scale the amount of air out of the vents up and down, if the actuator is failing? I thought that the actuator controls this, as well (or is there another one?)
Thanks!
Picture attached. In the top middle of the photo is the blend door, and the thing it attaches to with the screw is the actuator.
