Air Vent Flap and cable

[bhbarr]

Well, I cleaned up my interior and installed a new dash cap. The problem is... reinstalling the center heat/vent controls. Specifically..

I know the longest cable goes to the fresh air vent flap behind the blower motor... in my infinite wisdom, I didn't take a picture and now cant figure out how it goes back together... simple you say... well I disassembled the "L" shaped bracket and "V" shaped spring, like a dummy. How are they oriented to the pivot? A picture or diagram would be great!

Per your profile you have a

1972 240z? These pictures are from a heater blower from a 1/1972 car:

V spring position 2:

This writeup someone else did which may help some (or not).

The top lever controls

a) the fresh air vent that opens at the firewall vent valve behind the heater blower motor (the longest cable)

AND

the internal flap valve that ducts the air through the heater core OR straight through to the side and center vents in the dash. (the cable connected to the uppermost connection on the heater box on the left side)

(FYI: There is NO position for the heat to flow out of the side and center vents, you will only get fresh air ... or not.)

The middle lever controls the hot water valve. (right side of heater)

The bottom lever controls the two side doors on the heater box (left lower side of heater box). When the doors are shut the air is forced through to the defroster ducts, otherwise the air is allowed out to the "room".

Thanks Mike!

This solves my problem!

Long live the Z brotherhood.

bhbarr,

No problem. Yes long live the Z brotherhood. We will have to come up with a secret handshake though if we talk about it here it won't be a secret anymore. heh heh.

I am moving and the part you were asking about was under the house. Your question gave me an excuse to get the Z parts under there out and ready to move, no more putting it off. I didn't see any spiders either.
