Two problems related to horn assembly have been reported for the 1996 Volkswagen Jetta. The most recently reported issues are listed below.
Electrical systems failed and caused alarm to go off, power windows not to open or close. Took to mechanic, who replaced lock system which helped for awhile. Took it back again, and this time mechanic located electrical wires that had fused together under dash and were causing electrical failure.
