Snowplow kills the dash even after the harness update.

Anyone else still have this issue after having the TSB #124h UI Bulletin Intermittent Cluster, Radio and HVAC Display Resets on Snow Plow Trucks installed? I had mine done in this spring 3/2018. Used the plow once after the update and everything was fine. Put plow away for the summer. We had snow yesterday, 11/2018, so I dug the plow out hooked it all up to use and had the issue come back again. Almost like I never had it done. I checked the fuse and connections and everything looked good to me. There was some water in the fuse cap but nothing was corroded. I cleaned and put dielectric grease to keep water out.

We had this issue with either our 2015 or 2018 3500 and had the computer reprogrammed at dealership last year and has been great since then...

One of the bags of parts left in my new truck was (124x) - Radio HVAC IPC Blank Out When Operating A Snow Plow wiring harness. I talked to the dealer but they can't find anything related to my 2022 wiring system. Does anyone have experience with this?

Yes I have this problem 2019 2500hd w snow plow prep package. Had dealer install 8ft. Minute mount Fischer. After 5 times to dealership since I bought it new. Hooked it up after 2 years without snow and dash board goes off then back on when I use plow. Will be taking it in in March to see if they can fix it or lemon law and lawyer will get involved.
