Illumination fuse keeps popping (SOLVED)

[thegawd]

all of the components in the dash do have illumination in the switches. same in the door. on the door it's a brown wire. on the dash it's a grey wire. there is a purple/white wire that sends the signal for dimming the dash lights, not sure where it runs too.

Okay so I just noticed something on the schematic... fuse 14 is NOT any of the door window switches, or the mirror. so forget about the door... it's fine.

fuse 14 is only for this section.... so that narrows things down to just the dash switches. it could very easily be a problem with the way the radio illumination is wired... it's on fuse 14. say if they didnt use this wire and then it hits a part of the frame under the dash.... would pop the fuse.

focus on these components...

Thank you, this does help narrow it down.

This goes into the radio. Gray wire goes to the orange one on the right. It is frayed. Both the orange and blue are cut.

What do you think cause I'm running out of 10amp fuses lol

OH your almost there! see I like to solder and double wall shrink wrap aything like this. But I suppose the butt end connectors should work inside the truck, it's just not my style and I would never put these outside.

is this behind the radio?

Yes it's behind the radio, and I also like solder and shrink better. This is just how it came. I can redo it solder, but I don't have any shrink rn I'm thinking it shorting on the radio metal housing maybe?

Blue didn't connect to anything in the plug so figured pulling it out wouldn't hurt anything. Is that ok for the orange too, since the illumination is unused here? Just keep it pulled out like I did?

absolutly! do you have a multimeter to test for voltage and verify that the blue wire has power? I think it should and your right.

Blue wires behind radios can be for a remote accessory on or like an automatic antenna that rises when the radio has power... I have an RV deck sitting here that says the blue wire is for a powered antenna. the trailer never had one and this was just capped and wired out of the way...

Yup.....

I have no idea what the orange wire could have been... obviously the blue wire and orange wire are coming out of the plug that was used to wire the radio, right. so they have nothing to do with the trucks schematic....
