Horn not working when you press on the streeing wheel but will work on key pad for a chevy pickup 2005 year 1500

if you bought it with any warranty go back to the dealer you bought it from. if you push on the horn pad and you hear a click noise then the chances are the horn itself is bad. a horn must work to pass a safety. it could also be a BCM problem.

Check the Horn Relay (in fuse box under the hood). You will need to check for Circuit continuity between the Relay and the horn button. There must be a loose connection under the dashboard or in steering column. Pressing the Horn button Grounds the circuit, so check the circuit from the relay to the horn button for continuity to ground.

dead short at the horn button in the steering wheel

It could be the contacts in the pad but I would be more inclined to think you have a faulty clockspring under the air bag in the steering wheel.

Could possibly be a corroded wire, loose wire, bad ground. Not necessarily the wires going to it, but the accessory wire it is attached to. My horn worked when my vehicle was sold to me, then one day it stopped working. Never did anything about it, then 4 years later my power window stopped working. I spent 8 hours tracing out the wire and I found a corroded ground wire where it goes out to the door switch. I tested the power window and it worked and pressed the horn button..it worked too. Give it a try. Or you might just have a bad horn, try to tap it. It might work.

With test light check voltage at horn assembly on both wire's, could only have one, horn assembly itself could be ground, have some one press horn button while checking, if there is voltage replace horn assembly, if no voltage horn pad at streeing wheel bad. that's being fuse and replay are good.

sound like horn pad is bad.you going to have to replace horn pad and air bag as a whole unit.horn and air bag is all in one.this is a dealership fix.

try moving te shift lever up and down sometimes it will work other than that you have to pull the column apart to get the lock cylinder out

keep the steering wheel in one spot, do not rotate,  check horn by pressing pad in different areas.  If it is intermittent then horn pad is concern.  If it works well trying slowly turning steering wheel while pressing horn pad if there is a point in turning the wheel where horn becomes inop, then the common fault is the horn contact ring inside of the steering column

I replaced the malfunctioning “thermal actuator” with the “Warn” Vacuum actuator setup, it’s been working great for about 7 years now, simple install, if I remember correctly, it was about $150.
That’s what engages the front diff into 4wd.
