<VV> radio/ directional/horn problem

[jeandelucca at aol.com]

 on my original 63 monza coupe i have the following problem: occasionaly the radio volume will go low, but not off. tapping the horn will restore the volume to where it was. also the left front directional will not function all the time,, adjusting the socket will help, but believe it or not, tapping the horn will also mke the directional function. there is no problem with the front right directional or rears. i have checked grounds and harness connections. any suggestions? jim delucca
