Two problems related to horn assembly have been reported for the 2004 Chrysler Pacifica. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Chrysler Pacifica based on all problems reported for the 2004 Pacifica.
The horn for the car will sound indiscriminately. It will sound at any speed, any time of day, and even when the vehicle isn't running or has a key in the ignition. When the horn sounds, other drivers get distracted or confused by the sound. Driving with the horn on is also very distracting. I am uncertain if pulling the fuse for the horn will affect the airbag operation.
The windshield wipers and electrical systems failed during a mild rain. We got the vehicle to a Chrysler dealer and contracted for them to put it on the lift. We've learned that the main wiring harnesses on many 2004 Pacificas - such as ours - have collected water for years due to their design on the 2004 Pacifica, and have completely corroded. This substantially compromised our safety, as we exited the road having lost windshield wipers, all electrical, etc. , we attempted to use the horn which also was no longer working.
