All of the products sold by Jon Haas are excellent quality and he will stand behind what he sells.
but in your case I think you are perhaps selecting a solution that may not correct the problem you are experiencing.
The stock wiring for the headlight motors requires two functioning limit switches and if you buy Jon Haas’ conversion kit you will still have to use those same switches. The stock system also uses a relay which you would lose with Jon’s system
I would do some basic troubleshooting on the wiring, the relay, and most definitely the two limit switches.
Buying a new controller but finding the problem is your limit switches might not be a path you want to find yourself on?
