looked under the pass. side wheel well cover, no horn. decided to look at the fuse box inside the cab, the one under the steering wheel. pulled what i thought might be the horn fuse, it was busted so i replaced it (it is the 15 amp one, top row, middle location) & horn worked. i suspect the reason it busted was the right side horn activator on the steering wheel sticks open & it may have overheated before the previous owners got it to stop.
i can hear the horn but still can't find it. it seems to be on the passenger side but where is anyone guess.
thanks for the helpful suggestions.
