The OP has repeated that they are not mechanical. The thing that isn't clear to me is whether the OP wants to be mechanical. If you have a bunch of broken shifters, and want to learn how mechanical people visualize a mechanism working and how they use that knowledge to diagnose and remedy failures, then it sounds like the OP needs a mechanical mentor. You should find somebody who you trust and who is generous with their time and want to describe their process to you. Have them take one apart with you watching. Have them explain what they are seeing and what they think they want to do to fix your shifter(s), or tell you they are all hosed and throw them away. It's hard to be a mentor over a google group. Mentorship happens in-person.
If you can't find or don't want to find a mentor, maybe you want somebody to just try to fix them for you so you don't have to think about it? Again, that person should be somebody you trust, so if they say "these are hosed" you won't feel like it's a waste throwing them out. Again, it would be nice if it was somebody who was either generous or owed you a favor so that if they succeed, it's free, and if they fail, it's still free. People who work on things for a living are usually $50/hr to $100/hr pros and there's no way this project will be worth paying a pro what they deserve to be paid. Maybe there's a volunteer here who you'd mail your shifters to, and they can mail them back fixed. I don't know this for certain, but I think there's a non-zero chance that they are not even broken. The symptom described could be just a setup issue, as I understand it. The mechanic who does the diagnosis would be able to be conclusive on that. If you do decide your shifters are hosed, I recommend you upcycle them into key chains. Shift levers make great keychains.
