Happened to me once. I had to pull the cowl off the front of the hood and moved the linkage by hand and checked it all out. After I flipped the switch it came back to life and I haven’t had any issues since then and that was about a year and a half ago. Definitely couldn’t hurt to pull it apart and check your connections and clean out the cowl. Mine had all kinds of leaves and pine needles and shit in there. I cleaned up the debris and put some dielectric grease on the connectors and a little lube on the linkage too while I was in there.
