Two questions. First off when I turn the exterior lights on head lights work but the tail lights dont come on. But when I hit the brakes the tail light come on. So is there a fuse for the tail lights or could it be improper wiring.....also How do you remove the rear lock, do you have to break off the rivet holding it in? And how would you replace it if you did? cause I cant lock my car due to missing door keys.
