Sorry I didn’t reply sooner. I was having trouble viewing our conversation on the IRV2 site.
While I don’t have direct experience with working on the jacks, I was able to download LOTS of documentation from the jack manufacturer. I believe there was installation, operation and service/troubleshooting manuals. That would be a great place to start
Any time you would like to compare notes, I’m game! I have documented a huge amount of the electrical system. I’ve done a lot of work to the interior and dash. How long have you had yours?
