1) Starter relay near battery.2) bad ground connection.3) dirty battery cables or connections. A click is a indication of a limitation of current flow.
Depends on where it is coming from. If it seems outside of the vehicle, it could be a hub bearing.
Coming from the drive wheels? Could be worn CV joints
It could be a starter problem....can you tell where the click is coming from? is it the started clicking, or a relay clicking?
Possible a failing U-joint.
First check to see if you have a blown fuse. the horns are located under the front of passenger side front bumper. As for the clicking it probably is a fuse, actually the horn relay. my 97 horn's were burned out. found autozone replacement.
I suggest that you take your car to the dealer and they can help you there and tell you if there is somthing wrong with it or not.
That's your silanoid.. if you follow the + battery wire it leads you there, a lot of newer cars have it located inside the starter.. but that is usually a sign you need more power, try chargeing the battery or jumping starting it.. also make sure your cables are hooked to the battery tightly and the battery nipples and the termanals that hook 2 them are clean and shiny where they touch together. The clicking noise could also be coming from your exhaust system. Loose clamps or a hole in your system could be causing the noise. You may have to repair or replace your exhaust system. You can get advice on the same from magnaflow exhaust systems.
With a helper go to a car wash. Spray around the door and windshield with the helper inside to see where the water is coming from. This is the easiest way to find the leaks and plug or repair them.
Could be a problem inside the steering column
the clicking noise could be you lifters are starting to go bad or your valves might be bent a lil. eather you should just take it to the shop and have them look at it soon or you could blow your motor.
Could be many, many reasons some as simple as a small stone caught inside a hub cap.
if its coming as you turn it would be lack of lubricante in the cv joint or it could be the ball joint, as far as engine wise it could be your valves
