Sounds like a bad ballast resistor to me. Good thing is they are cheap (like $20)

Could also be the switch in the dash, also not big bucks.

My baby is a one of a kind.
1977 I bought a new 76 F150 club cab.
Sitting on a 84 F350 6.9 4X4 chassis
With all the drive train and goodies from a 95 4X4 4door PSD.
Nothing stock left on her and not a nut, bolt, hose, or wire on there that I didn't put where it is.

Themo King/Mikuni coolant heaters on both to keep things toasty without idling.

Look at the heater fan and just to the motors side of the fan you see a multi wire plug, that's it.
