Buzzer buzz’s after column rebuild

[Donnyboy1971c3]

1971 c3 350 w tilt/tel column
I had my loose tilt steering rebuilt and just installed column. It looks and feels great. I just removed the key with door open and the buzzer is still buzzing. It goes away when door is closed. My question is can I disconnect a wire on the horn relay so the buzzing stops until I can have it looked at? I have a crappy manual that doesn’t seem to have a wiring diagram of that circuit. I do most of my own work as I’m a mechanic on heavy equipment but leave some of this stuff to someone with experience.
Thx in advance

Hello, I have a 69 and I believe the horn relay is the same. If so there is a wire pluged ( not the screwed ones) on the left side of the relay that is the buzzer feed. Just pull down on it.
You said that the buzzer works with the key out and door open butstops when the door is closed? Just wondering if that plunger type switch in the front of the door Jam is acting up somehow. Don't know if that could do something. Good luck.

Isn't that door jamb switch for the cabin lights? Although it may have more than one function.

The continuous buzzer in your 1971 C3 Corvette with the key removed is typically the key warning buzzer (integrated into the horn relay on the driver's side wheel well), triggered by a shorted pink wire with black tracer (pink/black) to the ignition switch in the steering column or issues at the left door jamb switch. This circuit grounds through the door switch (3 contacts, including one for buzzer) and opens when the key is inserted/turned or door closes, but a stuck column switch tab, pinched wire, or faulty door switch keeps it closed.
Diagnostic Steps
Disconnect the battery first for safety.
Unplug the harmonica connector at the steering column base (1969+ style); if buzzer stops, issue is in column wiring like pink/black short to ground.
Trace pink/black wire from buzzer relay to column for pinches; test continuity to ground with key out.
Pull left door jamb switch (black wire for buzzer path); buzzer should silence if grounding there.
Check single gray wire at buzzer to LPS fuse panel socket; unplug to isolate (also silences headlight reminder).
Quick Fixes
Pull/tape the pink key buzzer wire at the harmonica connector (position F: pink 20ga) or buzzer relay's small-gauge pins to disable until repair. The column switch uses a plastic tab (often worn) to open contacts in OFF position; replace ignition cylinder if tab broken (common GM 70s fix).
