Underhood Fuse Question

Does anyone know what the 20A "washer no. 2" fuse under the hood is for? I ordered a new fuse box cover and it is exactly the same as my stock one except that slot is blank on the new cover.

 

Pull the fuse and see what quits working.

 

I assume a 2nd washer, you got headlight washers? rear window washer? ball washer? sunroof washer? Them turd gens be technological marvels.

 

I did that with no noticeable change in anything. My concern is that it may be something internal to engine during the injector self cleaning process/washing/etc. Probably unfounded, but there has to be a reason for it.

 

Hahaha definitely not that I'm aware of. The fact that the new cover left it off but is the same part number has me stumped.

I still don't see it. Weird.

 

Get yourself a “Sharpie” and write it in.

 

Anyone know how to split the fuse box on '18....trying to replace 120 amp

 

Got a pic?

 

Not at the moment. I'll try to get one later this afternoon.
