what's it all mean, heater controls Options

[theleschyouknow]

I understand how to get the best defrost cuz it tells me right there on the control panel but how do set the sliders for best cabin heat?
what does each slider control?
what do the three blue icons in the middle (| || |||) designate?
tried search here and looking at manual fixin to ask google but thought I'd ask the collective too

thanks for the reply yep I know it works (or worked) I've felt it on longer drives
not sure about blower none of the three settings seem to change airflow much and the fan light does not come on that I have noticed or recall

The HEATER blower motor is controlled by the lever on the floor near the gear shift. Open part way and the flapper boxes let hot air through the heat exchangers. Open a little more and the blower motor ground lead grounds and (in theory) you have the blower motor in the engine compartment forcing more of that "toasty" air through the heater tubes. The red knob on the dash only controls which direction that hot air (sort of) goes (to the left: underneath the dash at those outlets; midway: at the vents on the dash; full to the right: defrost outlets). I do not think there is a light for the heater to indicate it's on for the stock solution, but some people do wire it so that when they pull that floor lever the little lens on the left side of the controls will light up (you have to put your own light in there and ground it to the heater control). The lens on the RIGHT is supposed to light up when you move the top lever to the I, II, or III position. But that's ONLY for fresh (cool) air.

The car will eventually feel warmer with or without the heater blower working. Being that close to the engine (and if you have heat exchangers at all) will do that.
