I think this all operator error. I thought that "vent" would imply hot air blowing at you in the face. Instead it's just outside air, regardless of where the "fresh" knob is pulled to. So if I pull that flippy thing behind the shifter towards me, I get hot defrost and hot air blowing towards my feet (and a hot rear heater.) If I push it forward then I get cool air blowing at my face (regardless of "warm" knob setting), and a hot rear heater. I pull the "fan" knob once for a low fan up front, and all the way out for fan on high, and the rear fan- all that seems to be working great. So there's only two settings for the flippy thing on the side of the plasic duct, right?

Not used to these here climate controls... I need my buttons!

Flippy thing on the side of the plastic duct?

The lever on the left side of the heater should have three positions - one for heat/defrost, one for heat only, and then you flip it and it blocks off the heater core and directs the air to vent. The "fresh pull" knob on the dash only has two positions - fresh and "recirc" (at least as much as you can recirculate the air inside a 40 )

levers, knobs and clutch feathering - the wave of the future!

BTW Tim did you get your clutch fixed yet?

Ok, I think that thing is broken then, because I can only get 2 positions.. I need to look at another 40 to see what's different, then I'm sure I'll be able to fix it once I know what I'm fixing. thanks for the tips, all!

Yes, that my first deRomering. I bought a new master & slave from MAF, made a world of difference!

It had only two positions when I owned it.

deRomering . . . . careful you might find yourself lost in the Ozarks squealing like a pig.

Different years have different controls. I don't think the earlier years had defrosters, did they?

On the 77 there are three positions. Vent is outside air diverted toward your face before it goes through the heater core. This is to compensate for the removal of the cowl vent in 1974. Middle position puts most of the warmed air to your feet, and a little to the windshield. Position farthest back toward the operator is defrost only.

Prior to 1974 model year (7309), the front heater did not have the "vent" option because the cowl vent was still existing. Unlike the later front heaters, the early ones have an infinite adjustment of how much hot air is going to your feet or the windshield, completely mechanical analog control. After that it's either feet or windshield, although when you take the box apart you can see that some goes to the windshield even when it's in the feet postion.

Unlike most things Toyota did through the years, I think the later 40 front heater was a step backward in functionality and usefulness from the earlier arrangement. I'd love to retrofit an early style cowl vent to my 76. I can't (easily) on my 78, because the even the vestiges disappeared starting with that model year.

AFAIK, defrosters were introduced at the same time as heaters with the 1958 model year FJ25 in some markets. From the photos I've seen of the 1957 FJ25s, which were originally sold in Oz, those didn't have heaters at all. As late as 1982 some markets still didn't get heaters, although dealers sometimes retrofitted them, as they did with locking front hubs on USA models from 1963-1978.

My 64 had no heater originally.....the sad excuse for a black box it has now would still clasify it as no heater.

Curious, does it have the ports on the underside of the cowl for defrost?

With the advent of cooler weather in the USA, this topic has come up on the LCML recently.
