Hi guys,Starting work back on my 61 unibody.I had it sitting for many years behind my garage..Last summer I was going to pull it into garage and work on it but behind the glove box was a bumble bee nest si I left it till winter. Its getting late winter now so I pulled it around to garage and tore the glove box liner out and nothing there,They must have had a nest in my heater box. Is that box hard to remove and take apart to clean it out? I assume the bees are gone.
Just remove the face cover on the inside of the cab, some sheet metal screws, like 7 of them around the perimeter and that exposes the whole thing.. at least its that simple on the deluxe fresh air heater, not sure about the economy one.
Shouldn't be too bad. If you can get your hands on a Shop Manual btw, grab it. They are full of good information. Even jobs or stuff I've done many times before before, I'll read through some task and "why didn't I think of that."
It is important to clean out the heater boxes. I'm not sure how exactly, but they can get full of leaves or pine needles and all kinds of crap, it is a real hazard - plenty of trucks have been completely gutted by fire because of this! The heater blower motor has different speeds right? Well the way they do that, is by a big piece of coiled wire, a voltage dropping resistor. They get red hot.
