I've been reading this forum for a while to find the answers to a lot, but I just made an account because I'm having some pretty significant problems with my XJ and I can't seem to find an answer anywhere.

I was installing a new amp/headunit and didn't quite finish with the amp but the headunit was all hooked up and working. I'm completely new to any type of work with cars so odds are I messed up somewhere, but I had just finished wiring the power cable with the in-line fuse when I started having problems. I didn't even plug the cable into the amp because I don't have the ground attached yet.

Basically my problem started out just being that the new headunit and the dome light wouldn't turn on. I checked my fuses (both under the hood and in the car) and everything seems fine. I don't know if I just didn't notice at first (as I had the truck in my garage and only turned it to accessory) or if it happened later, but now my entire instrument cluster isn't working. The lights and everything work except for the gauges themselves. When I turn my Jeep on nothing moves, and the odometer doesn't go on.

Also when I had to drive it to pick up my sister it sounded like it was shifting at a higher RPM, but I haven't really been noticing it lately so there's a possibility it fixed itself or it might just be because I had been driving two much smaller cars for two or three days prior. Unfortunately, my only other car just got totaled so my Jeeps all I've got now and I'd really like to fix this.

 

my car it did something similar... the radio fuse had blown, and it was also causing it to throw a check engine light... weird stuff

 

seems fine, you gotta check each and every fuse by pulling them and looking or with test light/meter

 

i thought i checked all the fuses that could've been the problem but i decided to pull each one and check and i found the problem was actually a small 10 fuse under my hood--everythings working again!

 

Which fuse was it? I'm having that exact same problem.

 

Bump?

 

its one of the small fuses in the fuse box that is under the hood. there is only 5 or 6 of them i think. just take a look and you should be able to find it pretty quickly.
