My son stuck a screwdriver in the cigarette lighter of my 2004 chevy blazer I opened the fuze box interior one the 15A fuze was fried Replaced it but still the lighter doesn 39 t work Checked th

I don't use it for a lighter. Just for charging cell phone and GPS. When you sat the lighter element, do you mean the actual cigarette lighter or the !@V element inside the casing? I checked the 2 wires behind the lighter with a 12V light tester and have no power there. I replaced the burnt fuse inside the cab, and di not find any under the hook in the relay box?

When you said that the fuse was fried, it indicated that there is a short in the system somewhere. Usually, this is the element in the lighter, which is not your case, as I understand it now. It is possible that the fuse block may be damaged. You will need to test the connections at the block to make this determination. One easy test is to check the terminals at the fuse block. The hot side should register 12VDC when conducted to ground with a voltage meter, which it sounds like you are familiar with. If you have voltage up to the fuse, that's good. If there is no voltage at the fuse connector, the problem is in the supply to that fuse, and may be a bad wiring connection to the fuse, depending on how badly fried it actually was......Next, set your meter to continuity (the symbol on the meter is a speaker). Check continuity at the meter by touching the probes together. If set correctly, you will hear an audible signal. Place one probe on the non-voltage side of the fuse block, and probe the socket center terminal. If the electrical path is intact, you will get the same audible sound as before. If there is no signal, then that wiring is suspect. Either way, If I could not get voltage or continuity, I'd check the backside of the fuse holder first, as that is where subsequent damage seems most likely to occur.

ll my troubles and no success I double checked the Cigar fuse again, and saw that it was very slightly seperated. I also tightened all my connections and ground well. Tried it again and all is working fine. Don't know for sure what fixed it, but it's fixed, Thanks a bunch!! ll my troubles and no success I double checked the Cigar fuse again, and saw that it was very slightly seperated.
