Fuse number 6&9 keep blowing under the hood. - 2000 Lincoln Navigator

Test inspect harness and sensor for short

Try unplugging the power control module. If the fuse still blows its wiring if it doesn't I would guess the power control module is bad.

Check wiring for a short might have rubbed through and earthing see if it blows a higher amp fuse .

No diagrams? I'm working on a '95 cherokee, the cover on the box has a complete diagram on the underside. On the '95, there are 10 maxi-fuses, and 6 mini-fuses. What is the number designation of the fuse? Likely the numbers may not agree with mine, but I could try to help. By the way, if you have your owner's manual, it would show all fuse and relay descriptions and locations, both the under hood box and the under dash fuse block.

If it is a 20amp fuse in the passenger compartment its for the power door lock circuit.

You have a bare wire somewhere either in your instrument cluster or under the hood where the blower motor is. It's located on the passenger side behind your computer it's easy to inspect the wires there cause they are all exposed.If a bare wire is showing just tape up with electrical tape or duct tape to keep it from arking out. If not that check that aground wire isn't fastened somewhere under the hood or on firewall. Check wires from fuse box all the way through the firewall could be dangerous. Also make sure you have the right amp fuse in if it tells you to use a 15 or 20 or 30 amp fuse make sure you have that one in.A lower number fuse will heat up and blow everytime.

this problem is most likely caused by a fuel pump with high amp. draw on start up.use a amp meter.then replace fuel pump.

Check the wiring around the horn and make sure nothing is touching metal...look under the hood at the horn and make sure everything is pluged in and there is no water on any plugs or wiring...Make sure the fuse is the correct number (ex: 10, 20, 25) If it is still blowing out the fuse then you after you do some checking then it is a short in some wires

youll have to probe that elec.circuit to find what is causing your short
