need help on weirdness
 

okay i have a 1994 gmc jimmy 4.3 vortec w so this is weird
so when i blow my horn the high beams come on
or if i cut my high beams on my horn blow constantly untill my highs are cut off
so i'm thinking it a ground issue right if my guess is right
where should this groud be located
im hoping someone else had this issue and can share their solution
thanks for any help:icon_hyper:

sounds like your headlight wire and horn wire melted together.(or are just freyed and shorted out) follow the wire backwards from your headlight or horn.

do you have higher wattage bulbs?
