Question about 2005 Jeep Grand Cherokee

1 Answer

Power outlets don"t work

The power outlet and cigarette lighter don't work. I have replaced the blown fuse, but as soon as I plug anything into them (ie phone charger, ipod transmitter) the fuse blows. I have replaced it with a 20 amp fuse like it says in the book and have also tried ones aith a little more amp and all of them blow. Also the lights on the ac panel fade in and out. Sometimes all of them are on sometimes half are on and sometimes none of them are on.

Be sure what you are plugging into the outlet has the same polarity as the outlet itself. Some of todays accessories being foreign made have a reverse polarity versus american made cars.

Lighter plug seems burnt out

Even if the fuse shows no signs of being blown (one such sign might be a black spot), you might want to try a different fuse of the same amperage to make sure.
If the fuse is good, you have more work to do. Check whether power is getting to the outlet by testing it with a voltmeter or circuit tester. If the voltmeter shows power is reaching the outlet, the outlet itself is probably damaged from repeated use or simple misuse. Though chargers and other plug-ins are supposed to be of uniform size, some may be bigger or smaller than others.
time to get a new outlet then.

Power outlet

I would probably vote for the fuses again.
I don't know of anything else that three components would be connected to other than the ground circuit.
They could be wired thru the key switch and are probably on a different circuit than the cig lighter.

I try to find cigarette filter to replace the filter because my cigarette lighter doesn't work ( Toyota Camary LE 2000). I couldn't find it Thank you Somsak

Do you mean that you are looking for the fuse? The fuse for the cigarette lighter is located in the fuse block under the left side of the dash. it is marked "CIG". It is a 15 Amp fuse

NOTE: This fuse also powers your clock, air bag sensor assembly, remote control mirror switch and your shift lock. If this fuse is blown, you will also have problems with these items.

Your vehicle is also equipped with an auxilliary power outlet (Which looks the same as the cigarette lighter socket) it is powered by the fuse marked "*1" If this fuse is blown, only the power outlet will not work. This also is a 15 Amp fuse. (See picture below)

My cigarette lighter is not charging in my car what could it be?

You mean there seems to be no power to the vehicle's lighter unit outlet.

This lighter unit outlet is normally wired through its own fuse so check the fuse panel in the car for a blown fuse. If blown it must be replaced with a fuse of the correct amperage. The owner's manual will show you where the fuse is located.

Before you check the fuse just check the cigarette lighter outlet with another plug-in device if you have one such as a portable 12 volt tire compressor or a 12 volt plug-in auxiliary light. It could be that if you are using a charger from the outlet, the charger plug or wiring may be faulty rather than the car's power outlet itself. (These outlets don't usually give trouble unless the wiring has been messed with or the outlet itself has been damaged or abused).

If no device works from the lighter power outlet check the fuse as it may be blown.

Fuse blown on cigarette lighter Saturn 2001

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.

Cigarette front lighter is not working in my 2001Saab

Check ALL the fuses. pull them out an dlook. Also repace the one that is power for the dash/rradio/etc... even if it looks good.
If that doe snot fix it then pull the lighter out and test the wire going to it for power. If it has power then you might have a bad plug/ground. Replace outlet if so.

Both of my front Power/cigarette lighter outlets give no power?

I do not have a diagram for this but : Lighter outlets are a "high draw" item which will be served by a circut breaker, not a regular fuse. Circut breakers are small silver plug in items found on your fuse panel. Both units may be on different lines also because of "HI draw". I'ts also not really difficult to make a new circut for this, to add outlets where you need them, or to replace missing ones.
