Can someone please tell me what this "V" knob is supposed to do? I know it stands for ventilation, but can't seem to figure out what part is supposed to react when I turn it (got some 4-5 repair books, all mute on that point). The two ventilation plates on the sides of the body do not seem to have a wire connected to anything and open only when pushed mechnically.

Also, does anybody know what the little knob in the dash right next on the right of the "V" knob does when it is pulled?

PS: These knobs are in OEM positon and look OEM.

Also: Is there a trick to get the windshield washer fluid to sprinkle?

Anybody have advice where to best locate a hand throttle control - if in-dash?
If elsewhere, what's the best way to connect it to the shifter? I realize there was some discussion about this earlier, but it somehow took another turn. Any help is appreciated.

I am also looking for an un-rusted un-altered glove box cover with the 4spd shifting instructions plate on it. Anybody got one for sale?

Thanks in advance, Claudia
 
Doesn't the '72 have a vent in the top center of the cowl? It has a flapper door that must be controlled from the dashboard.

Isn't there already a throttle cable on the dash? My '72 partscar doesn;t tell me because the dash had been modified, but both the '65 and the '77 have them.
 
on my 71 the "V" in between the front and rear heater switch. It closes off the outside air intake so the heater is on "reciirulate" . The kick vents on each side are manual . The cowl vent pull knob is under the dash about center.
 
V should be a pull, not a "turn". :D
 
to honk:

from what I see, there is a choke, but no hand throttle. At least nothing else connected to the carburetor.

Thanks, Claudia
 
On my '78, the hand throttle is pretty much attached to the steering column on the right hand side.

I didn't even notice the thing until I made it home (5 hour drive) when I first bought it.

On mine, it's connected to the actual gas pedal, not the carb.
 
throttle should connet to the pedal at the firewall
on your wipers, do you get fluid through the line to the nozzles? if so, clean the nozzles out with a pin. if not, check power to pump and pump itself...can you hear the pump?
 
the V=recirculate would make sense, but i still have no idea what the little one does, ha ha....same deal with my 72

i only use the lights, wipers, and choke, occassionally the hazards and defrost, but the others remain a mystery....

Well, I could leave the others mystery as well, except for the fact that the wiring has imprints (weired splices) from all the POs, and want to figure out what unnecessary stuff I can eliminate. Claudia
 
The pull knob to the right of the Heater Vent pull is the room light switch. If you are getting rid of it, don't throw it out. Someone will want it and they are hard to find.

Dave, thanks, very helpful.

The V knob only turns and has a little spring that turns it back (like the knob motion that would activate the windshield washer). I guess the little knob on the right no longer works, since there is a new in-cabin light with its own switch installed.

There are two extra holes in my FJ, one left from the choke and one below it. Left of the choke, there is now a pull that has a yellow indicator light in it; does something electrical, and could be the switch-over to light control if the FJ is trailered. The position where the stock throttle control knob is in this picture, is now taken by a switch for a pusher fan that was just recently installed by PO.
What used to be front drive indicator light is now the ignition key location, and the hole next to it is just ugly and covered with a little clock. Former ignition key hole is now master ARB compressor switch, two separate switches underdash for f/r.

Would you happen to have a diagram showing where the throttle control knob actually connects to? That would help me figure out what I need to install. Thanks in advance.

Trying to figure everything out, I am learning about the preferences of the POs: one was a "bolter", another one clearly a "riveter". All of them seem to have had a knack for hack wiring, go figure..... I am reluctant to even try the CD player (some amplifier under the seat) for fear that the electrical gremlins we just managed to contain re-awake in full force.

You should be able to look under the dash and see a cable that goes from the V knob over the heater and under the heater duct on the right side to a vent on the dash wall passenger side forward of the kick vent. If the cable is gone, then Bob's Your Uncle. (whatever that means.)

I'll do more on the throttle cable later when I have picture access.

Are you sure the V knob only turns? My '68 V knob pulls out. It is a cable connected to the flapper door that controls air flow to the heater blower. Pulled out, the heater draws air from outside. Pushed in, it draws inside air through the vent on the firewall above the passenger's feet.
Look at the back of yours. If it's a cable, follow it to see where it goes, disconnect the other end and see if you can pull it out an inch or two. Could be the cable is rusted inside somewhere or the door is jammed, and the return spring you feel might be torque on the cable.
 
I also was expecting it would pull out. Pulled as much as I could, no movement. Being able to wrestle the steering wheel on this cruiser should provide enough evidence that I have sufficient strength. :D

Sorry about this, But I was noticing the turn signal light's are likr mine(#3), But I have them near the speedo too(#4 but not working).....Odd I alway's thought the PO rewired it weird.

chances are you've got the stock lights for that year (shown in the diagram) with non stock instrument cluster, from a later year. AFAIK 73 was the first year where the signal indicators were in the cluster
 
yeah, my 72 has the indicators outside the cluster...

also, my V knob is a puller....
