Been on a longish journey and needed to use the horn (to warn this numpty who was pulling out on me) but it did not work.
Anyway tried again when the moment of avasion had passed and nothing not a sausage. Hmm I thought another job tommorow, find out why. But also when pressing the horn the radio volume increased, interesting!
Anyway stopped off for lunch, returned to the car and later tried the horn, it worked!!!! Everything back to normal.
Has something reset itself? Have I just had a glitch?
