That wire is for the "Key minder" circuit. When the drivers door is opened and the key is in the ignition the horn relay buzzes as a reminder to remove the key. It along with the dome light are grounded at the door jamb switch. When the door is opened the switch closes to ground both circuits. I suspect this switch is not opening when the door is closed.

Elree you are faster than me this morning, but since I typed this up off-line I'll throw it out anyway.

No pun but it sounds like the relay isn't the problem. The orange striped wire is part of the key minder circuit. This reminds you that the key is in the ignition as you open the drivers door. When the orange wire is grounded the relay buzzes, which is what the relay is doing.
Problem is the orange striped wire is grounded. This wire goes to contacts by the key switch. When the key is in, these contacts close. The other end of the ignition switch contacts go to the left door switch. When the door is open, the wire gets grounded and makes the relay buzz.
I would disconnect the wire off the relay and disconnect the turn signal connector on the column. For safety disconnect the battery. With an ohmmeter, measure the key minder wires to ground on the turn signal connector (left door closed). This should tell you if the problem is under the hood, in the column, or towards the drivers door.
