Vadien Posted January 11, 2019 Share Posted January 11, 2019 I have a couple of electrical problems on my MJ that I suspect are related. Most of my gauges don't work. Fuel gauge not working at all, voltage not working at all, oil pressure works but showing weird nunbers (sensor might be bad), water temperature works. My blower motor turns on but is barely blowing any air at all. Like it has no power. Headlights turn on but are super dim and don't think cluster lights are coming on at all. Could these problems be a body ground problem or something? Link to comment Share on other sites More sharing options...
Pete M Posted January 11, 2019 Share Posted January 11, 2019 run through Cruiser's renix tips, especially the grounds and fuse box. should be like the first link in the DIY link in my sig. don't just do the one you think might fix it, do them all. Every MJ needs them all done. Link to comment Share on other sites More sharing options...

SVPete Posted January 12, 2019 Share Posted January 12, 2019 Start with Cruiser's tips. Cruiser54.com Another thing to check is that the electrical connector on the back of the instrument cluster in fully seated. But you gotta read and knock out many of those tips.

Mine does the same. Especially if you update to a newer sensor... On 1/11/2019 at 1:47 PM, Vadien said: don't think cluster lights are coming on at all. (dumb question) have you tried turning the pull knob for dim adjustment on the cluster? Link to comment Share on other sites More sharing options...
