you are onto something here. I have already been to the c217 connector and the red wire does go dead when the stuff isn't working. so now what it looks like is that wire is the supply? and it is by itself going thru the firewall grommet? and this was checked unplugged.

 

The red wire at C217 is the always on power for the two branches at the S223 splice which includes the entire list of dead fuses in the I/P fuse panel that you gave. I dont know if this is the only wire passing thru the firewall grommet (P100). Keep working your way back towards the battery when things are dead at either the C6 connector or the output of the Int Batt Fuse (easiest first check) in the underhood fuse box.

 

Power has always been good at the int batt fuse. I will keep on it. Looks like I am by myself this week so time on the Blazer is limited. I appreciate the help, and for hanging with me.

 

Then it's either the C6 connector or a break in the wire between the C6 and the C217 connector. Once we get this straightened out let me know what else is still not working correctly and we can tackle the rest.

 

will do, thanks.

 

Found it. On the bottom of the fuse box the C6 wire was bad right at the connector in the box. These are the wires from the INT 50 amp fuse. It was still connected until I messed with it some. It just wasn't putting the "full load" to the interior. I sure appreciate the help.

 

Wow! Nice sleuthing on both of your parts!

 

Did that fix everything?

looks like it did. Appreciate the help with the schematics George.

 

My pleasure. I live to solve problems, the harder the better.
