1994 Ford Bronco Blows Fuse #18 with ignition turned

[czejkops]

I own a 1994 Ford Bronco EB, that one day while driving home from hunting, I noticed the speedometer was not working, nor the digital odometer... Upon further investigating I found fuse #18 was blown, tried replacing and everytime I turn the key it blows.... This fuse controls: Speedometer, Overhead Temp/Compass, Airbag, 4WD Electric Shift, and Overdrive from what I have gathered... As I can drive, but no speedometer/odometer, no compass/temp, no 4x4 at all, and the tranny shifts hard with no overdrive... Not sure if it is a coincidence, but I have never used the 4x4 on the fly before that day, and used it 2x that afternoon, driving no more than 15MPH at the time. Any help would be appreciated. I have already done a thorough wire inspection on the entire undercarriage of the vehicle, transfer case included. Specs... 1994 Ford Bronco EB, 5.8L, AT, I have replaced the automatic hubs with manual WARN hubs, still have the push button 4x4 and 4x4 lo on the dash that was functional up until that day.

Welcome to the Zone >

I would start by disconnecting components that are on fuse 18. Easier said than done, but here are some diagrams from the EVTM. I would advise you get one, it is the single most useful service manual you can get for your truck. You can find them on eBay. Just did a search and here you are http://cgi.ebay.com/ebaymotors/1994-FORD-F...sspagenameZWDVW

Hope this helps.

Good luck,
