I have a 2009 Challenger RT. Lately I have been noticing when I lock my car with the fob the alarm chirp has gotten quieter and quieter like it makes my car sound like a little pansy. The some times it will sound like it normal should. Just yesterday I noticed when I went to lock my car the alarm did not chrip at all, but the turn signals and tail lights still all flashed like norml so thats how I knew it locked.

Does anybody know if this is a known issue or do you know what could be causing this? Its really bugging me, ESPECIALLY now that my windshield got cracked on the freeway on my way to work I really want my alarm fixed. Makes my car feel like its falling apart :crying:

Thank you family!!

Does the horn sound normal when you press the steering wheel? Horns do go bad sometimes.

Yeah, the horn is still working fine and normal on the steering wheel!

Dang are both the steering wheel horn and alarm chirp all connected together??

Are you suggesting maybe new wiring to use for the ground?
Or try to move the ground elsewhere?

Thank you

Well on my 2012 locking the car makes the horn chirp, I would think it's the same in 2009? Do you have an aftermarket alarm?

I am getting older and my hearing is getting worse. Maybe yours is too. Just a thought.

Do you live in a cold climate ? I am in NY and right now we are freezing our arses off ! My Saturn has the remote start feature and when its very cold out in the morning (after sitting all night), when I start the car, the horn sounds like a small fart ! I found out that the horn has some sort of diaphragm that gets frozen and causes the horrible grunt. My brother installed one of those train horns in his truck and his horn scares the bejeesus out you!

If the horn sounds normal when you push the steering wheel then I doubt the ground is bad.

I don't have access (at the moment) to the wiring diagrams, but there is another possibility.


A lot of automobile manufacturers will put the switch on the ground side (because, if the switch wiring shorts to ground, all it will do is sound the horn; wired with the switch on the hot lead, the same short can do a lot more damage). In that case, the steering wheel horn button may be on a different ground circuit than the alarm system.


...that is to say, perhaps the ground on the steering wheel button is just fine, so the horn sounds normally when using that. the ground on the alarm circuit might be deteriorating, though, and that would account for the weak sounding horn, when activated by that circuit.
