I was driving and the engine on my 2007 ford focus 4 door sedan just quit working, found it to be fuse 9 (engine management fuse) 20A, replaced it and boom, it blew again, where is my problem at? What is causing the fuse to blow?

Yes inside the car under the dash driver side. Go to this site and download owners manual, it is free. http://www.fleet.ford.com/partsandservice/owner-manuals

Fuse#16 20A fuse. Middle row 2nd column when looking at fuse box from a seated position

Check fuses. Make sure master switch is door switch is not off locking the rear doors fron openning. Check for power.

Thanks for choosing FixYa and welcome to the site. Your horn does have a fuse and it should be labeled in the fuse box. If the fuse is not blown, you could have a defective button, bad connection, or a bad wire.

fuse #33 a 20A is for the Sunroof

My car stopped running without any warning, its a 2005 ford focus, 2.0 and the 20 amp fuse for the engine management keeps blowing, it's number 9 in the panel and I have replaced it twice, both times it blew again, any tips? Also the odometer reads ------ and that's it.

check fuse 63 first.

Visual Inspection Chart Mechanical Electrical

• Binding latch mechanisms
• Binding linkage
• Misaligned door

• Central junction box fuse 63 (20A)
• Damaged wiring harness
• Loose or corroded connection(s)
• Circuit
• Door lock switch
• Door lock actuator

It could also be your GEM (generic electronic module) which is expensive as it controls a lot of stuff. A scan tool can be used to cehck for fault codes from the GEM.

your fuelpump could be causing the fuse to blow as it may be seizing up

Just had the same problem with my '05 van. I put the Master Switch in the off position. I pulled fuse #7 on the driver side sub panel, located just above the engine hood release. I then disconnected the neg. terminal on the battery. I manually opened the pass. side slider and closed it.

I reconnected the battery and replaced fuse #7. I put the master door switch in the on position. I activated the auto door switch, and it worked.
