Fuse #24 1999 Ford Expedition

You have a short to ground on that circuit ,the only way to find it is to find a wiring diagram an see what all gets power from that fuse .Then isolate each circuit until the fuse doesn't blow any more . Go to youtube an check out some videos on finding a short on automotive wiring . Also I suggest you check out some videos on basic automotive electrical trouble shooting . Finding an fix automotive electrical shorts is best left to a automotive electrical repair shop !

VERY LIKELY A BARE WIRE IS GROUNDED CHECK THE TRUNK FIRST.ANYWHERE THE WIRES TOUCH METAL COULD BE THE PROBLEM.

It sounds to me like a direct short I think you need a sparky to keep the cost down

You need factory wiring diagrams to work on any vehicle
If a fuse blows, it does so for a reason,& replacing it,is
not a fix.
Need a shop to work on the issue
If you loose one relay in 60 years of driving, that would be
a lot,so forget that,leave relay testing to people with
those skills

You'll have to start at the relay and check the circuits for a short to ground. Could be a faulty relay too.

I would say there is a short somewhere. You can get a resetable fuse.

pull your radio fuse and make sure your glove box is shut tight

When ever a Fuse blows, 1 time

You need to find the circuit,which you know

Next ,you need to have wiring diagrams
No diagrams your done,stop

You replace a fuse 1 time only

Then you have to diagnose the issues

If you can not follow that,then you have to
pay a repair shop

The same key should be the same for all doors.

could be many things. could be a short to ground. find out what wires work on this circuit. and check all the connections and insulation of the wires. if there was any sound system put in or recent electrical work i would double check the quality of that.
