79 f250 no A/c Non hi-output.
i am looking to buy the best quality replacement parts.
i see a lot of options.
I do not see a copper heater core tho.
from any ones experiences can you tell me where to get the good stuff ?
Do the Resisters even go bad? thanks

 

Did a google search for copper heater core and found these people. Don't know anything about them though.

And yes, resistors do go bad. They are made with several loops of resistor wire and the wires can burn through and break.
They're easy to replace though.

 

LMC truck shows a copper heater core, look them up on line, they got the resistor as well. Might as well replace the blower motor while there.

 

Thanks men. I forgot about LMC. after seeing the schematic on there site. Looking at the parking brake set up on the frame where the front cable connects to the back cables.
its Shows a arm with a spring and a threaded rod for adjustment. on my 79 f250 is that what i should have? when i got the truck it does not have that set up?

any light on this subject would be helpful. thanks

 

The Ford parts catalog shows the 78-up F250 uses a slightly different set up.
