When I use to use my remote to lock my 2008 Frontier the horn would blow once and the headlights would blink twice. When I unlocked it the lights would blink twice. Now when I lock it with the remote the lights blink twice but the horn doesn't blow. Also now when I unlock it the lights don't blink at all. Does anybody know why it's doing this now. I checked my fuses and they all looked good. I also tried using a spare remote that I have which is brand new but that didn't work either. I guess I could recheck my fuses to make sure that I didn't miss one.
