2000 Toyota Tundra

Electrical problem
2000 Toyota Tundra V8 Two Wheel Drive Automatic 165, 00 miles

I am having problems with my horn. I have tested the horn under the hood and they work. I have checked the fuse and its fine. The dealer says that there is no relay on my model. In the past (this has been a problem for three years) I would take apart the steering wheel and clean the contacts on the horn assembly and it would work but only for a short time. Now I cant get anything to work PLEASE HELP

Dealer will tell you anything if they aren't getting paid. the integration relay is what controls the horn. it is located on driver side junction block and should be labeled "integration relay" .
