Just got a 96 explorer sport, and when I got it the windows wouldn’t roll up. I checked the fuses and saw that fuse 27 was blown so naturally I put a new 15fuse in and it started working. A few days later the windows stopped working again and I check the fuse and again it’s blown. I put a new one in and almost instantly the fuse was blown. If I’m right it seems like a short circuit right? Any ideas on where to start looking bc when it comes to the wires in a vehicle I’m not the brightest one. Any help is appreciated

Check the drivers door hinge wiring. Common for these to break the wiring inside the door, or just on the other side of the hinge.

So to clarify, check the wiring that’s underneath the sleeve in between the door hinges?
 






And inside the door itself. The wires flex and are probably brittle by now.

I checked inside of the door itself and the wires look good, trying to figure out how to check the sleeve without tearing it. Thanks I’ll let you know what happens

So I took off both door panels and connections were good on the panels, look inside of the boot on the driver side and they all appear to be intact. I’m honestly stuck at this point
 






okay so yes the common place for the short circuit to appear is inside that black rubber boot on the drivers door. It can be a PITA to loosen it and have a look in there but it is necessary

here is some help for how to access the boot and have a look see

Okay so lets start with the fuse
#27 inside the cab protects
Under hood lamp, map lights, glove box lamp, dome lamo, visior lamps, accessory delay, dimmer switch illum., 4×4 system

Nothing about power windows? except the accessory delay circuit

I would check the accessory delay relay it maybe bad, It is related to power windows and it is in the only thing in the circuit fuser 27 protects that s related to windows
Also check all the light bulbs and wires to and from in that list above, circuits protected by fuse 27

see here:

The main power window fuse is under the hood in the large power junction box

I have a book that tells how to troubleshoot the power window circuits deeper than this, but this should give you a place to start

ok, I'm just getting around again. I'll definitely go through these steps and see what comes from there

after spending some time looking at all of the wires, I'm like 95%sure I can rule out wires. For the time being I may have made a mistake of disconnecting the window from the regulator so I could at least manually move my window up. At least until I am able to grab some testers. I also found the fuse box under the dash in the driver side. But I upon searching for information on which one of those relays is the accessory relay but couldn't find any. Any chance you know which one it is? If I remember correctly, there are four relays in there, is there a way to find out without testers if they are working? Or would it be time for me to add more tools to my bag and grab some testers?

Also, some new information that could possible help, the windshield wipers are not working as well. Is there accessory relay power the wipers as well? Not sure if that kind of helps point in a certain direction but I only realized the wipers aren't working whole driving it and I had a dirty windshield.

the information definitely helped me out some! I actually ended up unbolting the door from the frame so I could really pull back the boot and I didn't see any wires that were corroding. None showed any obvious signs or being damaged either, that I was able to see. I was working on it in the day time with a head lamp for extra visibility. Aside from pulling out the parking brake, I wasn't able to spot any damaged wires leading out to the door. So I'm starting to think it couldn't be any damaged wires? But I could be wrong. I don't have testers aside from a makeshift one I have to see if the power is coming to the fuses or not.
 






I had this issue, was a short circuit in map lights in overhead console. 27 fuse protects is interior lighting circuit, however if it blows the windows die also.

Do the map lights work? Check the sockets, look for the conductive film, and see if any of the material is touching the other side of circuit. Also check dome and glove box lights. GEM module could also be suspect.

none of the interior lights work aside from the dash. No glovebox, visor, overhead (this be the equivalent to the map light right? I'll double check it) and hood light as well turn on.

Reading through some of the forums where people had similar issues, some pointed out the GEM module as well. TBH I'm not sure what I'd be doing there but I am always willing to learn and figure it out through the headaches, after a puff or beer or two haha. Thanks for giving me another direction to look at turdle
 












I'd try disconnecting overhead console, then see if fuse blows with it disconnected
ok fasho, I'll definitely give this a try. that'll tell me if there's a short circuit somewhere along those wires right?
 






No, that will tell you if the problem is in the overhead console.
