? for Brain Trust, Air box flapper adjustment Options

[hndyhrr]

The flappers Should be closed when the red lever on heater controls is all the way to drive side....

I had the air box out awhile ago and when I got ready to reinstall I (thought) that I set the rod underneath so that they closed and opened on both side at the same time.

HA HA on me.

One side closes and the other opens. HUMMMM no wonder I get blasted by heat no matter when the dang slider is.

How to I adjust this with the cable? or that damn rod?

that is a pic I grabbed from the interweb, Mine is in the car.

Help Please

feeling not so Hndyhrr right now.

Thanks

The dash heater controls do not control whether or not you get heat. They only control where the heat comes out of; above the dash or at your feet.
To allow or block heat from entering the cab, you use the lever that's located on top of the center tunnel to open /close the heat flapper boxes. The boxes are located right behind each long on each corner of the rear firewall.

Thanks for reply.

The heat flapper boxes work as they are suppose to.

i guess my question is the flapper things inside the the air box. those should both turn in the same direction, either both open or both closed. Mine .... one side open on side closed.

Robert is correct.

The “heat” lever on the dash only directs the hot air up or down. Turn the heat off with the red lever between the seats. Red lever down is off. Hot air is blown out the flapper valves below the engine compartment.

The fresh air works exactly the same way. The Fan lever first opens the air flap on top of the air box letting air in through the grill under the windshield. The second lever directs the fresh air up or down (or mix).

All 3 dash levers fully left and the heat lever between the seats down closes the air box completely.

This assumes of course, all cables are connected to the levers and flapper boxes are there and functioning. Flapper boxes are prone to rust and can freeze open or closed.

They should both be open and close at the same time

Someone has jacked with your box

Fixing in car (IMG:style_emoticons/default/confused24.gif) - never tried it and access is tight and visibility is terrible. I personally don’t think it can be done in car.

One of the flapper door levers is 180 out. Been years since I’ve had mine apart for a complete rebuild. If I recall you have to split the fan housing to be able to get the levers in the same orientation

Not my photo but hopefully helps you see what needs to be done.
