help with tr6 horn

["Mark S. Lepore, M.D." <Sirmoog@ix.netcom.com>]

Hello:
I could use some diagnostic help.  My horn used to work intermittently,
but now doesn't work at all.  I used to have to press pretty hard on the
horn push, but eventually it would sound.  Does anyone have any advice
for diagnosing a horn problem.
Thanks in advance
