Interior electrics not working but truck runs?.

[DieselFam]

Excursion runs fine. Headlights tail lights and turn signals all work but nothing in the cab works. No windows, seat adjustment, instrument panel, overhead panel radio or interior lights. I don't have an owners manual and I am pretty sure it's a fuse but which one. Need help. Thank you

Well you can always just check them all with an ohm meter.
And what year? Cause I'm sure someone has a 6.0 manual but you may have a 7.3

[DieselFam]

Sorry. 2002 excursion 4x4. I'm pretty sure it's a fuse but not sure which one and if it's everything it would be a big one. Not the little small ones. Fuse panel under drivers kick panel has zero information on it except "consult owners manual".

I've got the manual on PDF. Want it?

[DieselFam]

I just ordered one. Stupid of me not having one already in any case, does the manual tell you where the main fuses are? Or is there a diagram?

Here is a better question. Can I run this thing until I can get it in to a shop Monday? It's the wife's and I would hate for her to break down.

Upon further inspection. The overhead is on but not working. It shows zeros for everything. The instruments aren't working at all but the instrument cluster back light turns on with the head lights. The only instrument light working is the little ABS light that comes on when you turn the key on.

It may be a fuse, it may not. Could be the GEM but usually there is drive-ability issues with that.

[DieselFam]

Seems to drive OK. I guess I could just start pulling fuses and see.

[jesilvas]

Or ohm them out. Or get a test light.
Seriously, you can pull fuses and still it may not do anything and be something completely wrong.

The back of every blade style fuse has each side exposed enough to touch a test light to, in order to quickly see if one is blown. If it has power on one side, it should have power on the other side.
if not, no power is going through the fuse.
