85 D250, 318, 435, D60 no A/C.
I can't find the heater control valve for this truck under the hood or
looking thru the glove box opening.
It has heat flow all the time and doesn't shut off by the controls.
The truck was on a farm in S.E. CO before I bought it for an
indeterminate period so the valve may have been removed rather than
Does anyone know where it might be or should be and if it is a cable or
vacuum operated valve (no a/c just heater from factory).
