How Long Does It Take for a Car Horn to Recover After Getting Wet?

[MichaelMarie]

Car horn recovery time after getting wet depends on the extent of water ingress. Below are two scenarios of car horn water ingress: Minor water ingress: In this case, no special treatment is usually needed. Simply allow the moisture inside the horn to evaporate naturally over 1 to 2 days. Once the water dries, the horn will return to normal. It's best to remove the horn and reinstall it after 1-2 days when completely dry. Severe water ingress: This situation requires disassembling the horn and using a hairdryer to blow-dry it. The heat from the hairdryer will accelerate the evaporation of internal moisture. The horn will function normally again after drying. If not addressed promptly, it may cause circuit short circuits and horn failure.
