Nissan Sunny honking the horn easily burns the airbag spring
Q: My Nissan Sunny easily burns the airbag spring when honking the horn. I have replaced seven or eight springs. How can I solve this problem?
A: Analysis shows that it may be caused by the back electromotive force when the horn works or stops working. Please check the horn relay. Generally, as long as the diode in the horn relay is damaged, it is very easy to burn the airbag spring.
