Subject: Horn Sounds Unwanted - keywords alarm corrosion electrical fuse horn intermittent relay UBEC water #PIC4673 - (11/12/2007)

Models: 2005-2008 Chevrolet Corvette

Condition/Concern:
Some customers may comment that the horn sounds unwanted. Removing the Horn Relay in the UBEC will disable the Horn. Further inspection of the relay and UBEC may show water intrusion. This is typically caused by "power washing" the engine compartment.

Recommendation/Instructions:
Remove the horn relay and allow the UBEC and relay to dry. (Do Not drive the vehicle or return the vehicle to the customer without a functional horn). Once the relay and UBEC appear to be dry, reinstall the HORN relay and the concern should be eliminated.

Note: It is not recommended that high pressure washers be used to clean under hood. If used extreme care must be used to not target electrical components and connections as the sealing systems used can be over come by high pressure water.
