So i have an 04 RL, while looking around to find a mysterious flapping (plastic bag under the wheel) I noticed that i have a third horn on the inner frame rail on the passenger side. but it doesnt seem to work, it looks exactly like a horn but if i set off the alarm by opening a door or panic button it does nothing, what gives? i searched but didnt find anything really...

 

Can you take a picture of it? I'm curious....although maybe it's remnants from an old aftermarket system (not likely though).....

 

You can kinda see it, it looks like a horn from my 99 tl that was the actual security horn.

 

Looks exactly like an older stock horn. Very weird. Is it plugged into anything? Any electrical connections?

 

yes its plugged in with a plug exactly like the front main horns... it is strange, i want it to do something though haha

 

lol I would too. Follow the wire and see where it takes you lol. I'm trying to picture where exactly it is, I want to check my car and see what occupy's that space.

 

in the second set of pictures, the first one has the large cooling fan on the passenger side. if you take the lid off your air filter it is a lot easier to see.

 

Okay, when get some free time in the next hour or two I'll go out and take a pic of the same spot and see what's there.

 

I was under the impression that the RLs came from the factory with only two horns. Because in my 98 RL that was crashed (granted it is not an 04) I found two horns in the engine bay and took them out and put both of them in my replacement RL for a grand total of four horns, it's pretty darn loud! , but after I took those two out and when I pressed the horn button in the wrecked car, no sound came out, so therefore it had two. Maybe a previous owner of your car had a similar situation but was only able to find one of the horns.

 

There are two horns...one hi one lo I believe. I have both of mine hooked up independently of one another, so If my alarm goes off, there's two very different horn sounds going off (to get attention).
