It's been 5 or 6 years since I changed things inside the auto heat controller and I've forgotten everything I did to make the blower fans stay on. Part of getting old I guess.

Go back into it and while turning on the autoheat watch the servo motor turn the inside thing that pulls the cable and watch the microswitches being triggered by it.

Try tripping the micros witches with a finger or whatever to see what you need to do to them to make the fans stay on. It can be done and the poster above changed some wires around on one of them to do it.
You just have to experiment until you find what works.

I kind of wanted to keep the box because I mounted my MSD boost retard knob on top of the box where it's easy to get to while driving if I hear traces of detonation and a couple flush mount rocker switches in the side of it to do other things.

good luck with it.
