horns
 

Getting ready to pull the front bumper cover, clean the radiators and maybe install mesh over the intakes.While I have it off I want to check the horns as they are not working. I have checked fuses and changed the relay ( I think I changed the correct one, but not sure. Mine is an 04 boxster S and the schematic I saw was a 2000 or 2001 ) but no luck. I don't hear a relay clicking when I try the horn. Anyone know of a step by step check list to isolate the problem? thanks mountainman

Odd one. You might want to remove the airbag (read up on how to do it correctly) and check the connections there.
