12v outlet fuses keep blowing.

door locks and cig lighter ARE NOT on same circuit. Maybe lighter is broken and blowing fuse.

First step would be to use a bright flashlight and examine the socket (receptacle) closely for the cause of the short. You may be able to remove it. If the fuse blows when you try to use the cigarette lighter, the plug lighter element may be faulty and need to be replaced. These lighters are pretty standard and you could try one from another car that you know works properly to help diagnose.

some cig lighter outlets have a U shaped + center pin.
Sometime yer plug's - will engage it. ooops . Look for the two sides of the U and mark the edge of the outlet with red nail polish. Then when inserting the plug with a side pin, orient it away from the paint. Keep more fuses in the glove box

Replace the lighter it is shorted out, the lighter is Held in by a big stamped nut on the bank of the threaded barrel.

2 different things, and remember the 2 others are for 12v accessories not a lighter

Shud be same,look if fuse box has others incase,M

satlite reciver may have a short

It sounds like you have a bad charging cable for the GPS or the cable is overloading the cigarette lighter.

The cigarette lighter is designed for less power then a 12v power outlet.

Therefore it is easy to blow the fuse for the cigarette light if you install something that draws too much power.

Most likely you have something metallic that entered/fell inside one of the cigarette lighters.

I once found a dime inside a cigarette lighter which my children assured me was placed there by a shadowy personage named "Notme". Go figure.

While the fuse is REMOVED, look inside each lighter with a flashlight and remove the foreign material.

If you find nothing inside the lighters, disconnect them all from the electrical system by removing the single wire attached to the rear of the lighters. Replace the fuse.

Alternately, you can disconnect them one at a time, replacing the fuse after each one. You may need a few fuses for this.

If the fuse blows after ALL the lighters are disconnected, you have a wiring short circuit which is best diagnosed by a professional.

If the fuse does not blow, begin reconnecting the lighters until you see a spark, or the fuse blows again. This is the faulty lighter, replace it and your problem is solved.

Note: You cannot get shocked or electrocuted by your car's 12 Volt system but you can be burned by heavy sparking. You can reduce the risk of heavy sparking by using a lower-rated fuse during the testing. Wear saftey goggles and latex gloves for safety.

Good luck

First off the reason for instant fuse blow is because this is a positive wire grounding out or touching/crossing a grounded surface. I would first target the Cig lighter outlet connections also if the outlet is rusty inside looking, replace it.
