Atc fuse keeps blowing. I traced all the wires and can not find any obvious shorts in the wiring harness. Repeated 4x4 fuse blowing usually indicates a short circuit in the transfer case control system. try to replace fuse but it blows as soon as i put in. Some of these systems use just one 20 amp fuse for both. I unhooked the actuator and the push button 4 wheel drive selector and tried to put a 20 amp fuse in it and it blew that right away. So for the heck of it I checked the fuse in the driver side dash fuse panel and it was blown. There’s three of them (ato25 fuses) and I was told to shut fridge off before plugging it in to shore power but when when it’s plugged in with nothing on it still blows the fuses after a few days and they’re even burnt and the plastic is bubbled. We would like to show you a description here but the site won’t allow us. Not an HD truck, just plain 1500. I did this with about 5 more 20 amp fuses and it did it to every single one of them Oct 27, 2019 ยท Hey everyone, started my 2005 Silverado with 30K miles that has the push button 4wd and got the service 4wd message right away.
