Blowing Fuses

Any ideas on what could be blowing fuses in the lighter and power port on an 08 F350? If blows them as soon as you put the fuse in with nothing plugged in.

Have you looked into the plug itself to see if anything is stuck inside and shorting it out?
Other than that, you'll just have to follow the wiring until you locate the short. I would start at the lighter/power port end.

You may already know this, but the only thing that will do that is a short. To find exactly where the short is you will have to trace the wiring. My guess would be a pinched wire somewhere.

I agree here. Many times I've seen things in the recepticle, mostly coins, causing immediate shorts.

Unplug the lighter (easy to do) and if it doesn't blow), you got your answer.

Double agree. Screws and pennies... pretty much anything a preschooler can find could be in there. I speak from experience (4 preschoolers).
