I'm sorry the Expert you requested was unavailable to assist you today. It appears that Tech is currently "Offline". Now that his 15 minute "request lock" has expired, hopefully I can be of some assistance in his place. Sorry for the delay.

Your horn circuit dose have a relay and its incorporated into the the CJB (interior fuse panel) and if its actually bad it is not service separately and the CJB would have to be replaced. That being said, there are two fuse that power the horn circuit. One is located in the under hood panel, its the F2- (50 AMP) fuse and the second one is the F14 (20 amp) which is in the CJB. I have enclosed the wiring diagram to check the circuit if both fuses check okay in the link below. Copy and paste the link toy our browser to open and view it. Have a look and post back if you have more questions and or need more help.
