Cigarette lighter and auxiliary power fuses have both been replaced with new fuses, but neither plug has power. #65 is empty, too. There are a surprising number of empty slots. I mapped those that are filled, if that helps with the diagnosis.

My model does not have anything in the Cigar. Mini Relay slot. Do you have any other diagnosis suggestions for this issue? Yes, I looked under the left rear seat and found that position #58 is empty. I acquired the car 6 month ago. The cigar. And aux. Power worked until last week. Thanks.

Hello,

There is a relay and a fuse to power the cigarette lighter, use a test light to see where you lose the power at. Here is the wiring diagram and a guide to help you test for the problem and some diagrams (below)

Electrical problem
2003 Buick Lesabre 6 cyl Front Wheel Drive Automatic 90000 miles

The cigarette lighter works intermittently - and we need it to power accessories such as the Ipod - I have checked the fuses which are fine

There is probably a bad wiring connection. Posibly behind lighter housing.

I have replaced the fuse for my cigarette lighter (#23 on the fuse box) but only one of them actually worked. I want to know how I can fix the other one and if there is another fuse for the other cigarette lighter?

Fuse 22 powers the auxiliary power outlets, fuse 23 is the actual cigarette lighter. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

There is usually a cigar fuse. Maybe the heating element is faulty? As far as the fuel gage, could be issue with sending unit--wiring circuit--or instrument cluster. Give me a second to find wiring diagrams.

Yes, check the cigar lighter fuse, also, check for voltage at the fuse circuit, hot all the time.
