Fuse #15 in my 02 Expedition keeps blowing. I have changed out the BOO switch and the brake shift interlock but I still blows immediately or sometimes it works for a while but in the morning it is blown. Has anyone had this happen to them.

My guess is that the power wire has rubbed or been abraded by something moving against it. I would be checking around those windshield wipers since they are used a lot and they have a lot of movement.

Unplug the componets on those circuits till it stops blowing the fuse then you know what wires or componets to look at.

The 97-02 Expeditions had a problem from the factory where the windshield was not sealed correctly and tend to have leaks on the drivers side right above the fuse panel. I just had to replace mine. I would be willing to bet that there is moisture built up behind your fuse panel and it may need replacement. Either way you WILL need to get your windshield resealed as Ford never released a TSB or recall for this problem. This also causes your GEM module to go out which controls alot of the chassis electrical components.

Curious Mreinhar if you resolved this problem. I have the EXACT same problem, fuse #15, on my '01 Expedition. I live in San Diego, it hasn't rained here in six months, so I know rain/leaks in or around the windshield are not the problem.

@jehall find out what components fuse #15 protects. Find them and unplug them one by one till it stops blowing the fuse

Check the brake fluid reservoir, there is a sensor for the fluid level mine was leaking into the plug causing it to short out. I unplug it and replaced the fuse and now it works.

i have the same issue with my 00 but the fuse pops when I shut the driver side door
