Hi , like i said in other post , i've bought a 1999 blazer 4 door.
I bought it in an auction . At the auction the're was air horn into it,The next day when i came to get the car , no more air horn.
When i try the horn , nothing happend at the moment...
maybe the old owner disconnected it?
May sound stupid but where it's located?
Thank you!
I'm now a Blazer FAN !
Thanks!
(i've checked the fuses and they seems ok!)
