Air horns stopped

The air horns work with the key off, key in the accessory position, but horns will not work with key in run position.  Could it be the R8 Horn Relay Part#2166A3?  The Air Solenoid works!  Doesn't make sense.
Thanks, Mike Wolfgram

Best guess.....The electrical relay that runs the horn usually has a NC (normally closed) and a NO (normally open) set of contacts. The relay must be under the driver seat in the electrical bay on the right buss because that buss is activated with the ignition. I would check the horn relay leads and see what contact lug they are on (NO vs NC)and switch the relay wires around that heads out to the wiring for the horn. Some relays do not have both type contacts in which case you would need to replace the relay with one that has both the NO/NC options.
