Having problems with your Nissan Pickup ?
2005 Nissan 1400 Standard. The hooter buttons on the steering wheel works intermittently. The ******* themselves work OK. I would like to know what to look for?
First locate the horn in the engine compartment should be between the front grill and radiator core support. Pull the horn off, it has one wire and one bolt holding it on. next clean the bolt area where it is bolted on with sand paper to get a good ground. Sand it on the bottom of the mounting bracket and on the area where the horn bolts on. next get a wire and hook to the positive side of the battery, touch the horn to the negative side so it has a ground then touch the horn wire connector with the wire connected to the positive side of the wire does the horn work? if so it was needing cleaning, if not you will need to replace the horn. There are two things that you can do before you replace it look for a single screw on the horn and back it out three or four turns the try it again before installing, if this makes it work better then you know the problem that the reeds are going out replace the horn for $15.00 at any auto parts store. Or buy a air horn for $20.00 bucks and replace it with that, it's louder and easy to install. Nissan has always had issues with the horn so your not alone on this issue. Also check to see if a wasp built a next inside the horn or a mud dauber may have built a nest in the horn, if there is obstruction in the throat of the horn clean it out and try it again. Of all Nissan's I have worked on I have found it necessary to replace the horn about 90% of the time.
