Horn Change
 

My dad owns an e53 x5. his horns went out, both of them. I'm looking for the instructions on how to replace them. I know they're located on the left, front bumper. Can anyone clue me in as to the easiest procedure to replace them? (i wonder what caused them to go out in the first place) At 85 bucks a pop i hate to change out the horns only to have them go out again. When i get them out i'll bench test them. It looks like i'll have to take the front bumper off, which seems like no big deal... i just don't like surprises as far as working on cars is concerned. thank you for your input. this seems like a great website.

ps: i own an e34 535ia... her name is Gretchen... gosh i love that car.

Yup they're under the front bumper. I added a 3rd louder horn but eventually took it out so I've done this twice. Pics here: http://www.xoutpost.com/x5-e53-forum/...-pictures.html

Yep I have changed mine out to a simulated air horn. If you unscrew the driver's side headlight and slide it out some, it will give you more room to work.

With both of them not working, I would check a fuse or maybe the switch in the steering wheel

in my case only one horn does not work. how do I test which one to replace?
