It’s been over a month and I think it’s solved. Repair was easy. Diagnosing it was the hard part. Very difficult to diagnose an intermittent problem. Spent a lot on unnecessary parts but I’m sure it was still less than having it flat bedded to a repair facility. I got a big education on Gems for the next time. I also labeled a lot of wires because I’m sure I won’t remember if I have to go through this again. Thanks again to all that helped. I could never have completed this repair without the wiring diagrams.
