My 2005 Honda Civic Coupe has a factory alarm. Lately, when I arm and disarm the alarm the exterior lights do not flash like they used too. The interior lights come on, and when the alarm is triggered the lights flash then but not when arm/disarm.

Perhaps a relay is blown?

If so, where is that relay located?

I have checked both interior and exterior fuses and none seem to be blown

 

take it back to honda....sounds like it needs to be reprogrammed/reset.
