2005 Chevy Malibu Classic, horn
not working, fuse blown. When I try to replace the fuse, horn blows continuously. Horn relay OK (swapped with another relay). 12V constant on energizing coils of horn relay. Alarm button on key flashes lights, but 12v remains constant on horn relay.
Would you suspect short somewhere, or stuck 'horn switch' in steering wheel? How can I tell? Wiring diagram in Haynes manual does not show any horn wiring. There are 6 wires coming out of steering wheel. A white and a green wire go into a yellow outer covering (I assume these are air bag). A pink, a blue, a grey, and a black and grey wire go into a black outer covering. I assume these are cruise control and horn, but don't know which is which.
Is horn switch actually part of the air bag assembly? Is it replaceable?
If I have to remove air bag, Haynes manual indicates 2005 and earlier has 4 'holes' that you have to insert flat blade screwdriver and twist, 2006 and newer has 2 holes that you just press a blunt object into. My 2005 appears to have only 2 holes.
Thanks for any assistance you can provide.
