just got an mkIII (95 )and it has an after market steering wheel, it has a horn hook up but the horn doesnt work, the horn worked for my alarm but not for my steering wheel. now all of a sudden the horn for my alarm doesnt work....

i checked the fuses, and the wiring in the eingine bayis fine up to the firewall then i loose it. what am i looking for in the steering column for wires?
Any Suggestion?

 

If you can access the button test it to make sure thats not the problem. that will also give you an idea of what color wires youre looking for.

 

very true! and i know in mine...which is a mk4..but i had an mk3 as welll, and you might have two horns. mine does now, one for alarm and one for steering wheel. but i have no clue why the alarm one worked for a bit and now it doesnt. sorry mang!

 

Can you hear the horn relay close (pull in/click) when you push the horn button?

 

make sure you check all the wiring to make sure that nothing has came loose!
