    Need some help here guys. Have a 2005 vnl780 and my rear blower stopped working. It's driving me crazy!!😁😁 well I bought a new motor, that didn't work, of coarse checked all fuses, they are good. I even switched rear control panel with one from another truck.. Same thing no good. I changed speed from 1-4 from the rear panel or from front dash and nothing happens!!! Is there some famous short or something for this I'm missing. Can anyone help?

    You are guessing and that leads to spending $$$, get a test light or meter, then you will see what the issue is..

    theres a harness with a connection (6-10 wires not sure)behind the wall directly in front of the driver side service door check if they are corroded because that very well maybe your issue

    Marek thanks for tip sounds like I have a mission this weekend forsure!! I followed the bunch of wires from the blower along the edge of the workstation lip and it seemed good but don't think I got that far. This was 3 months ago .. Made it throught winter with only front blower, wasn't bad but in summer with no a/c back there it will be a oven. I'll update after this weekend😃. Now when you say behind the wall do you mean remove the rear panel by service light? Thanks for all the help

    You want to remove the panel inside the driver side storage compartment directly under the bed right below where your sleep control panel is because the harness will run straight down to the plug in question behind the panel where it i think runs under the rubber floor
