Does anyone know where I can get a wiring diagram for this Blazer? Preferably free... I need the diagram for the FUSE BOX.I fuse keeps blowing as soon as its put in, so we think that if we find where the wire goes,we could fix it...
Yes,we tried the auto parts store and they don't know...
The socket for the fuse is marked FCMB... no on seems to know what this stands for... We are a bunch of shade tree mechanics whose searching skills are sad and whose wallets are thin.
Can you help us?:(

Whoa, buddy!
Slow the bus down just a little. Most of the people who respond regularly here are very capable and are most willing to help, but we don't carry a pager.

Schematic diagrams are all over the internet but few, if any, are free.

Tell me which system isn't working with that fuse open..
Anybody on that end got access to a digital camera so I can see that fuse block?
Can you tell me what size fuse is supposed to be in that socket?
We await your response...

You are right, Im sorry.
I will try to explain.My grandson has a '92 Chevy Blazer s10 Tahoe. After running fine,one day it just refused to start.We thought that the fuel pump had gone out and tried to fix it(you know what that entails)... turns out that that wasn't what was wrong.After asking everyone we thought might know,we came to the conclusion that there is a short in the wiring somewhere.
We noticed that a fuse was blown.We put in another,it blew immediately.Again,same thing.
We by-passed the fuel pump relay and it still blew the fuse.. Both with key on and off.That is why I mentioned the fuse seat was marked FCMB.I thought that maybe we were not putting in the correct fuse... Anyway His grandpa and he are trying to figure it out and granny(me) gets to help in the only way she knows... ie:you guys... My grandson is 17 and probably knows how to post a picture.I don't.I will try to get him to post one tomorrow after school.
Thanks for your response and sorry for my rudeness.It was along day.
Cecilia

Here's what I would do. Online you can go to the autozone website. There you can look up your wiring diagram and trace back the problem side of the fuse namely one side of the fuse should be hot ( electrically active), verify that first then using the wiring diagram follow the path back to the component . Buy a multimeter and learn how to one . It will be the best thing you ever did. Without paying someone THIS IS YOUR FIX lol. Peace .
