Yesterday i was driving... everything worked! horn.... ash tray plug! everything! I was headed to o'reilly auto parts store to pick up a mirror for the coupe. Well I left my radar plugged in and Walked back out probly? I say about 15 mins later (give or take a few) walked back out to my car and my radar is off... Thought to my self hmmmm ok maybe i turned it off? well I press the button to turn it off/on and it wouldnt turn on!? so i took it out pluged my phone charger in and It didnt work ethier... Thought to my self hmmm fuse? bought a fuse changed it... Still doesnt work! ive checked both the radar and phone charger in the truck and they work!
Well today i was driving and this random car pulls out in front of me! went to honk my horn and it doesnt work ethier?


Short version

Thanks - Johnathan
