Hi my name is Robert...

Sorry for the delay I see not other experts have responded. In a case like this what I would do is get a 12 volt test light, turn the ignition ON and probe each fuse for power, it is a quick and easy way to see which fuses have power. You can ground the clip on the test light to the steering column. Run into this a bit where the fuses are not marked and a test light will show which fuse does not have power.... Hope this helps some, IF you have more questions or concerns please feel free to contact me... Robert

I had already done all those things and am still unable to find the issue. Hence why I asked if someone could direct me to the fuse number or the name of it as per the box number. Aka an expert in Chevy 4500 who was familiar with this specific fuse box

Please keep in mind I have no idea what you have tried. I will put your question back up for other experts, maybe another expert will have a print for you. I do not know when another expert will respond, they come and go daily... Robert

Hi I'm Wayne

I will help you with this

both are on the same fuse,it is a 20 amp Yellow fuse

so if 1 is working and other not, not fuse

with your test light, probe the middle terminal in the housing,

most times this is the cause either burned out, or wire came off the back of it
