xjrev10 Posted November 26, 2014 Share Posted November 26, 2014 Down to the finishing touches on my MJ project and I been working out the last kinks.... This jeep has had trouble with tail lights, turn signals and brake lights since I got it. Well I found the issue after a hour of chasing wires.... The fuse spot for the hazards/stop is destroyed. The one was that was attached fell off. And it goes to what I imagine is the flasher unit. Here is what the fuse looked like before I pulled the block off firewall for a closer look. Looks like someone was in there before... What are my options? I don't know much about electronics. Is there a way I could just solder in a inline fuse holder? Where do I cut? Or do I need to swap the block out? :( Link to comment Share on other sites More sharing options...
az comanches Posted November 26, 2014 Share Posted November 26, 2014 I've heard that synthetic brake fluid will not eat up the fuse block. Can anyone confirm this. Link to comment Share on other sites More sharing options...
joester1908 Posted November 26, 2014 Share Posted November 26, 2014 hmmm what issues are you having? Like none of them work? Some of them work? That's obviously an issue, id try to see if you can get it to make a contact. Are any wires melted? Link to comment Share on other sites More sharing options...
xjrev10 Posted November 26, 2014 Author Share Posted November 26, 2014 I've heard that synthetic brake fluid will not eat up the fuse block. Can anyone confirm this.Brake fluid will yes. Not sure about synthetic... But that's irrelevant in this case. No brake lights, no turn signals, no hazards. Running lights work. I couldn't get it to contact at all. Tried a few different fuzes. Once I pulled it apart, the wire just fell out. Link to comment Share on other sites More sharing options...
Eagle Posted November 26, 2014 Share Posted November 26, 2014 You need to replace the fuse panel. I don't know if synthetic brake fluid is corrosive, but I think it is. DOT-5 silicone brake fluid is not corrosive. It's pricey, but the clutch doesn't use that much. Link to comment Share on other sites More sharing options...
xjrev10 Posted November 26, 2014 Author Share Posted November 26, 2014 Ok. Easier to replace fuse panel or dash harness? Heard through the grapevine there was a tutorial on CC somewheres...for replacing the fuse block. Link to comment Share on other sites More sharing options...

tugalo Posted November 26, 2014 Share Posted November 26, 2014 On the firewall side, there are two wiring bundles that come into the fuse block. Remove the dust covers from these bundles, between the two bundles there is a bolt that holds the connectors to the fuse block. Remove the bolt and separate the two connectors from the fuse block. There will be lots of black gunk in the connectors, good time to clean it out and check for corrosion. Then go under the dash and remove the two bolts that hold the block to the firewall inside the cab. You will have to remove steering braces and some bracketry to get the block down on the floor where you can work on it. find someone on this forum who will sell you a fuse block, or go to a junkyard and cut out a fuse block from a Cherokee and have it on hand for the next phase. get a thin piece of metal and slide it down the sides of each pin you want to remove. Each pin has a metal tab that locks it into the block, and you must depress this tab toward the pin to get each one to slide out of the block. As you remove each pin, insert it into the new block. There is another post on this forum that talks about fuse blocks and has a link to a company that sells pins. Open this link and look at the photos of the pin and you will see the metal tab sticking out of the side of the pin. The photos help you visualize how the pin is made and where to use your removal tool to release the locking tab. Link to comment Share on other sites More sharing options...
