see picture for where it is. however, it may be inside the module and not replaceable and needing a scan for codes by a mechanic. check wire leading to horns either with a test light or volt meter for power.

See the guides below for using a voltmeter and test light, also for testing wiring

reread my reply if it's in the module you will never find it as it's an encased relay
