just like it says, if i try to use my lighter it will blow my horn fuse, plus my lighter still doesnt work, any ideas?

 

dont use lighter
you aparently have a short in the lighter and lighter and horn are probably on same fuse cant remember.check the ligter itself with a known good one like a freinds then check the wires for a short or cut wire.
if it was me since i have no use for a lighter id thow it out for a good 2ounce weight reduction should be good for 7tenths of a second jk

 

lol alright, i never use the lighter either, but i might get a radar detector soon and wanted to get it fixed, so i'll check it out thx

 

yeah once my radar detector made my ligher blow the fuse. It is the same fuse as the horn.

 

That is some type of omen to stop smoking If Phillip Morris finds out about this he might file a class action lawsuit against GM for the problem you are having. Good luck
