Stupid Buzzer

04Z71Blackout · May 20, 2009

I was workin on my brothers steering column in his truck, 89 K1500 automatic, because the steering column and ignition cylinder were messed up, column loose, and my mom drove it the other day and forced it in gear so now after I got it all fixed and put back together the only way the key in ignition buzzer will go of is if the key is all the way on. Won't go off even with the key out lights off everything. Any suggestions as to what this might be?

definately a mismatched wire

I haven't messed with any of the wiring though is why I don't know what is wrong

I thought for sure that would be a problem. I'm just as dumbfounded as you...

In my 92 GM factory service manual, it shows a switch for "buzzer" which looks to be behind the key switch. It appears as though when you stick the key in, a small rod sticks out of the key switch and activates this switch?? The drawing is very poor, so I can't tell much by looking at it.

And in my 92, the buzzer is called the "Audible Alarm" and is a black rectangular box located in the convenience center to the left of the brake.

Anyway in my book this stuff is located in the steering column section of the service manual, but you have to hunt for it. What I found was in the drawings of the whole steering column.

thanks for all the replies i currently have the "audible alarm" out of the truck as it wouldn't turn off... as far as the button you are talking about could that be it since it is a brand new ignition lock cylinder?

Apparently the lock cylinder has a little lever which pushes on this switch. And when it is pressing on this switch (because the key is inserted), the buzzer sounds.

The factory service manual has very LITTLE information on this, but does seem to indicate that the switch can be adjusted by bending the contacts on it or something.

It would not be worthwhile to even look at a factory service manual for this, basically you are on your own, as not much of anything is covered for this subject! (At least with my 92 manual.)

So just got to take it apart and figure out how, when the key is inserted, it presses on this switch, then figure out how to adjust it or modify it so it works. Or disconnect it.

By the way, the buzzer should only activate when the driver's door is open. If door closed, the buzzer should not sound.

Note: In my electrical diagram book, it shows this key-in switch as being a part of the turn signal switch??? Whereas the service manual shows a separate switch! Perhaps the separate switch just electrically connects to the turn signal switch?

Anyway the wires for the key in buzzer in my 92 electrical diagram manual are Tan and Light green. It shows the tan as going from the steering column to one of 3 connections on the driver's door switch and the tan wire is used only for the key-in buzzer. So if you wanted to temporarily disable it, I suppose you could remove that wire from that switch.

Note that this is for a 92 and I have seen vehicle manufacturers switch wire colors on stuff like this like night and day. One year this color, another year, that color! And sometimes different colors than what is in the electrical diagrams for that year! (So don't count on these being the correct wire colors for your vehicle...)

I had the same annoying problem with my '88. As said, I disconnected the tan wire from the connector and 'Key-In-Switch' buzzer/function went away.

I then unplugged the female seat belt connector to remove of the annoying (same buzzer) seat belt buckle buzzer/function.

This leaves the Lights On alarm and has came in handy.

Our Chevelle and El Caminos (70 & 71) had this sort of buzzer that would not shut up. The buzzer was part of the horn relay, so killing power to that box killed the horns, you had to disconnect a the right wire. I think the Skylark had that too, but it was a completely different beast and couldn't find the buzzer.
