How can I remove the horn relay from a 1995 buick lesabre

I believe it is the fourth relay from the left passenger side in the engine compartment against the firewall. I am assuming your horn intermittently goes off by itself. It's a interior heat related issue. The horn pad cover on the steering wheel has a membrane layer. It's basically a switch that has one wire that goes to the horn relay to activate the horn. The Buick GM logo embossed on this plastic cover is where I found it most sensitive to any light touch. Unhook the battery. If you carefully cut the right edge of the the steering wheel horn pad and carefully pry it out a little, it will fix this issue and still be able to use the horn. It's another GM defect. I hope this helps! Let me know.
