Well, my friend, you are certainly in a pickle. Here's what I would do. I'd call the service manager, being super respectful, even if meaning you have to bite your tongue and explain your issue. Based on what you've said, finding the issue is going to involve a lengthy search. I'm not sure what your relationship currently is like with Lazydays but I'd certainly try to patch it up. They messed it up, they need to fix it. There isn't an easy fix here as there's no way to determine what was 'fixed', read changed, on your coach during the repairs. So, your wiring/jacks/relays etc. may or may not be as the factory installed them. I had my coach worked on and they bypassed a couple things to get it working again but other things stopped working. It was a mess to trace down the inept work they did. I finally talked to the service manager, set up an appointment and told her I was devoting the entire day or two to getting the coach fixed and I'd be in their waiting room for however long it took. Then I showed up with all my goodies to make myself at home there. I was out in four hours. Best of luck....Dennis
