I recently bought a used 2000 gmc sierra, everything is running and working
properly...well almost everything. This morning I woke up to the sound of
my horn blaring, it was going off for no apparent reason. It has does this
once before and I have no idea why. It always happens very early in the
morning and when it is pretty cold outside, if anybody knows ANYTHING
about why it's doing this please fill me in asap. also the car has a few
custom things done to it i'm just wondering if that has anything to do
Could be the door light switch. If it is sticking, it can fool the
computer into thinking that there is a breech in the security system.
Something basic to check out. My 2000 Cavalier was doing the exact

I would suspect that you have the GM Passlock II system. Do you have a key
fob to lock and unlock your doors? If not, than I doubt it could be the
door switch. I'm not sure that year had the keyless entry or not. But, if
you are already having problems with it than check it out anyway.
I do have the remote entry but it doesn't work for whatever reason, my car
was broken into recently and hasn't been the same since. When the horn
goes off it's a steady sound there's no chirps or anything only constant
horn, and why does it only go off in cold weather? I pulled the horn relay
and of course it stopped I just hope I can still drive it without that in
haha yea i did it. I'm just not sure how long the horn is going before I
get out there and tunr it off. It was too early and too cold to sit out
there and mess with it so ijust pulled the relay think that'll cause any
Might be a warped steering wheel horn pad causing contact with the horn
contact inside the steering column - thus blowing the horn.

when my truck was broken into they ripped up the colom and the horn panel
and the steering panels had to all be replaced, plus previous to being
broken into I had the same problem, same time in the morning, but i just
hit the horn and it stopped this time when i hit it it didn't stop so i
had to pull the horn relay. I'm still not certain what the problem is? all
idea are appreciated and being looked into
It was warped, well the column wasn't warped, but the metal plate behind
the Horn column was warped to one side and was very close together and
when the weather got cold enough it would cause the plastic to condense
causing the wire to touch the metal plate thus making the horn go off.
awesome guys! thanks for the input really helped out. now only if someone
knows why my remote entry pad doesn't work or if anyone knows how to
Unplugging the horn relay will not effect anything except the horn.
Everything you know as normal should be just that without the horn. There is
a way to program te fob, and I have it here some place, when I find it I'll
send it via email. I've also read it on here someplace also.
You most likely on the right track. I once owned a Caddy with a
"rim blow" steering wheel. One could blow the horn by squeezing
the wheel When it got cold the cover would contract blowing the
horn. Try removing the cover and placing a thin piece of foam
under it, then replace, WBMA

Yea it's pretty weird when it only does it like once a month and it happens
only in the early morning, since i live in vegas that's about the only time
it's cold. I just ordered the part, if it doesn't happen again it'll be
worth it, it's only about $20
