Three problems related to horn assembly have been reported for the 1999 Toyota Sienna. The most recently reported issues are listed below.
I have a 1999 Toyota Sienna, bought new in April 1999. On November 11, 2005, I had to have the horn fixed because to make the horn function, you had to turn the steering wheel. It cost me $399. 35. The dealership listed "poor contacts in clock spring; replace clockspring". I now have the same problem again. I am wondering if this is an inherent problem with this type vehicle. Toyota will not help with the expense as the warranty is only good for 36,000 miles or 3 years. Have you had any other complaints regarding this type of problem with Toyota vehicles? in all the years and with all the cars we have owned (we keep the cars for many, many years) there has never been a problem with horns not working; that is why I feel this problem is inherent with this model if not other Toyota models.
