I may take apart one of these here to see how complicated it is. I can often stumble through automotive stuff of which I've never actually done or seen done but some things are just beyond my ability. I tried soldering aluminum A/C lines and just couldn't get it right. I can weld but will be taking a welding class at the junior college to get better at it.
I am okay with letting professionals do some things that I just can't figure out. If it gets to be too frustrating, it makes sense to just walk away.
Thank you for responding. I was hoping for a trusted member to chime in. I may just check in with you.
