So the other day I beeped my horn at a friend and it sounded ok the first long beep then the second beep the sound changed - not sure if there are 2 horns in an 07 and one died but now the horn does not sound right. What & where to I look for as I hate the new sound.

Help ...& thanks in advance

 

Make sure that a dirt dauber has not made a nest in the horn,or something has not clogged it up. Also check your electrical connections to the horns. They are located right behind the grill on the passenger side.
