Yeah, I knew/know about the coolant factor. Do a lot of my own mechanicals.

It was definitely a problem with the blower doors, it's been coming on for a while. I just needed that exact tip from someone who knew exactly what I was talking about.

Already got it adjusted, and heat flowing.

Thanks again.

Now that's what I'm talking about!!

Reddit wins again.

And man I love r/Vermont!

I knew about the heat control valve, and had that set right, and I knew there was something under the dash. I figured I'd ask for specifics before going fishing. And you delivered!

Now I have heat!

Thanks kind internet stranger, for taking time out of your day to write that out. It was exactly what I was looking for. Virtual beers to you my friend. I'll pay it forward.

Thanks. That's exactly what I was looking for. No way I would have found them through Google without just guessing some keyword. Didn't even think to search 4x4.

Problem solved, thanks to comment below, but I'm definitely going to be taking it in there for any future mechanicals.

Thanks for the tip. That was the backup plan.

The part issue really sucks. Mine has only 210k on it, is in great shape, and I will be f'ing pissed if some little unavailable part takes it off the road.

Inexcusably wasteful business practice.

Anyway, have heat now thanks to comment below.
