Sleeper blower issues - aarmon89 - 01-12-2023
I have a 15 prostar and i’am having issues with my sleeper blower turning on intermittently whenever it wants. It’ll even turn on when the truck is off and I have no clue as to why—which in turn eventually kills my battery if the truck sits for a few days

Do you have the bunk temp/fan controls in your dashboard? Sounds like either a faulty switch, happens, but still rare… Or, a bad relay switch. Where is the relay for the bunk fan? Good question, as I have no clue. I would look in the fuse panel first, there are relays in there. If there is a blower motor or rear HVAC relay, you can pull it for a few days and see if that solves it, or simply replace it. That is where I would start.

When the brushes in the fan motor start going bad they run intermittently.
should also not rule this out either...
