I have a 2002 F-350 7.3L Crew Cab. When I shut the drivers door from the fully open position, the #42 Aux. 15A Mini Fuse blows, which shuts down the radio.

Any ideas ?

Thanks in advance.......

 

iT IS THE RADIO FUSE, comes on with the ignition, wire color is pink, cant tell you why this would blow though, unless you have something loose on the speaker.. but even then..

 

For giggles, take a meter to the bottom of the fuse, and open and close the door slowly, may be were the wire come to the door. I am looking for anything else that fuse controls now. Sorry, you will want one lead to the bottom of the fuse, the other to ground.

I can not find anyting yet in the Haynes manual, still looking though

 

I checked from bottom of #42 Delayed Aux. Fuse to ground, while opening and closing door very slowly several times with key off, and found no short. My meter showed open the entire time. To verify I had a good ground for ohm check, I put the meter on voltage and turned key on to see if I saw the 12vdc, which I did.

 

At the bottom you saw the 12vlt, if you did, I am sorry should have had you at the top instead.

 

I checked from the top #42. The top showed no 12vdc when key is on. Turned key off and checked for short. Nothing in Ohm or K Ohm, it showed open. When in Meg Ohms it did some number jumping, but NO direct short. I had my son help, so we could do it very slow.

 

i am sorry, but the only thing that fuse does is the stero. it has to be the speaker wire, or speaker

 

Would you happen to know how the door panel comes off to expose the speaker, and wires?

Thank you. Should find the problem once the cover is removed. I will let you guys know how it goes. I really appreciate the help.

 

Welcome to FTE and keep us posted.

 

Thank you. We will.

 

Anything???

 

First let me say thank you. I was putting it off until I just read your post. I used the link provided by SpringerBob about door cover removal. Had the cover off in 3 minutes. You were right. He had to do with the speaker wires. The door plunger that goes in and out of the inside of the door had caught the speaker wire and was shorting it out. I fixed wire and secured wire bundle away from plunger.

Thanks for the nudge and knowledge JAT. Repaired in 15 minutes. Thanks to you also SpringerBob.

Good luck to both of you.

 

How did the problem occur?

The plunger coming in the door hit the wire bundle, which finally broke the plastic holder that held the bundle. When the holder broke it allowed the bundle and the speaker wires to get even closer to the plunger. The plunger finally focused on the speaker wires pinning them behind it every time the door was fully open, resulting in them shorting out.
