No heat in my 69 fj40

[Richard]

I have a stock 69 fj 40 in great condition except no heat.
Ive replaced all heater hoses (except to rear heater), thermos stat, radiator and hoses.
It runs at a perfect operating temp.
I did replace both short hoses going into the front heater core. Im not sure wich one is inlet or outlet. or if it matters.
The blowers continue to blow cold air.

Any Ideas?
Thanks, cold in Carson City

I also have a stock 1969 and my hot water comes from a valve on the head that you must either screw, or unscrew so water gets to the front and rear heaters. You did not mention anything on that. Maybe it is having issues?

This, and secondary inline valve that works off the pull knob on the dash (if it has one).

Ok, I just went and looked at it. Wire conection was pretty corroded I cleaned it up.
Is there any way to check it or what else can i do?

It does have a pull knob on the dash. Is that for an eloctronic switch on the valve?

69 should not have a pull knob for the heater valve. The valve is just a manual turn on n off style. Its on top of the head just behind the carb...with the heater hose coming out of it.

the valve lookes like that except its got an electric wire conection on the peice just south of the circle on the diagram. Im a little confused with the electrical.
The valve isnt a butterfly but a 14 mm nut. looks like a nipple on it.

However, ive got heat now that I manually opened it.

Part of my problen is that I dont know what all the controls on dash panel are for.
If I had a pic of what all of the knobs do I could maybe make some sense.
Thanks again for help

the piece just south of the valve is your water temp sending unit.

The knob under the dash with the squigly lines opens/closes the cowl vent that is below the windshield.
The "V" knob on dash opens closes the fresh air flap that lets fresh air into the front heater or pulls it from the interior.
The 2 "H" knobs are power for the front and rear heater.

Other knobs....choke/hand throttle/hazard/wipers/and the small one is for the dome light. my 69 is converted to floor shifters so I don't have the old vac transfercase setup. So your dash layout may be a lil different.

Like 3 puppies said...that electrical device just infront of the heater valve is your water temp sending unit.
