Looking for some advice regarding horn issues. I have a GGH20W 3.5L 2010 Alphard.


My horn intermittently works, there does not seem to be a pattern behind the issue. 


The problem may have arose after my toddler would continuously slam on the horn the second he was able to get to it. Usually his brother would unclip him when the adults were busy dealing with something else after the car was parked.


I looked at some YouTube videos and the closest I can find is a someone talking about the horn on a Toyota Sienna. The relays seem sensitive and may be the issue.


Does anyone have some pointers about how to approach the issue before I start decompiling my steering wheel?
