Blown fuse when using 4 wheel drive

Hello everyone, I have a 2010 Tacoma and recently when I put the truck in 4 wheel drive it will blow a fuse every time. Any idea what the problem could be?

 

Start simple. Look for frayed wires, e.g., a short, bad switch.

 

What fuse is blowing?

 

10A Fuse for brake lights and shifter gets stuck in park

 

Only when you put the truck in 4wd?

I can't see how it would be related, the stop lamp circuit is not connected to the 4wd system in any way.

 

It happened a couple times earlier in the year and was good all summer because I wasn't using 4WD. Then a couple days ago we had a snow storm and I used 4WD and the fuse blew, replace it with a new one. Truck was working fine, had some more snow this morning and I put the truck in 4WD and the fuse blew again. So yeah maybe it isn't related but it seems like it to me

 

Does 4WD work?

 

Yes works fine

 

I really don't think it has anything to do with engaging 4wd, I'd start with inspecting the wiring in the rear of the truck behind the bumper.
If you have a converter box for the trailer plug you may try unplugging that, those can cause all sorts of issues when they fail.

 

Yeah it seems to be in the converter box for the trailer plug. Thanks guys!
