AnswerFirst thing is go find the fuse. Use a test light to check the fuse while it is still in the vehicle. If you have power on both sides of the fuse then you know that the fuse is good. Next, check for power at the horn, probably located on the left front wheel well, right front wheel well, or in the grill. Pull the wire to the horn and stick your test light into the connector. Have somebody push the horn while you see if you have power going to the horn. If you have power to the horn, you probably need a horn. If no power to the horn, you either have a broken wire or a bad horn switch (located behind the steering wheel).

My 2005 Nissan Altima is doing the same thing. The car has no heat when the car is stopped. You have to be going at a steady pace for it to stay warm. I have had the car looked at, at a Nissan dealership but without paying $800 dollars it can't be fixed..and there is no guerantee that it will work after the work. The dealership guy said he has alot of people complain about the heater in the 2005 Altima. Nissian won't do anything about it he said.
