I have a 2007 STR8. I was using a Air Compressor in the Cig Lighter when it stopped working as I was putting are in the third Tire. Compressor was running about 10 min. I checked all 20 Amp fuses in both under the Hood and the Trunk and all were fine. I plug another accessory into the lighter to ensure it was not a problem with the compressor and it did not work. If it is not a problem with the Fuse what else could it be?
