2002 buick lesabre windows wont rool down horn wont honk

i would check the ground out inside the steering wheel before anything else. these can get bent or broken off during a good panic honk or during a fit of roadrage. once ok'ed i would have a helper with a test light or volt meter check the system as you honk the horn to find out where the voltage stops. where the voltages stops will be the problem

1 behind the battery, and opposite side of car.

its possible that the relay is the problem as most relays have a second power feed wire,if it shorts to the horn side of the relay it can blow the horn.doesn`t happen very often but it does happen.this could explain the horn blowing without the fuse in.you can get a door key made at a lock smith to solve that problem.

Sounds like a short in the circuit, which may or may not be in the steering wheel. It might be, if hitting the horn button actually stops it for a while. Be careful with the airbag and remove the fuse before messing with it- I've heard a slight short will set it off.

no. the horn switch is underneath the airbag, and if the horn is activating itself late at night (when it is cold) then the switch is most likely what it is. the cold makes the plastic around the airbag and switch contract, causing the horn to make contact. if you want to just silence the horn, you can remove the horn relay in the underhood fuse box. should be labeled in the owners manual

here is how you do it, it is not easy. the system u have is called the VATS Passkey anti-theft system. go to the link

sounds like you have a short in the horn wiring or a bad ground wire these grounds are mostly located under the engine compartment near the back wall whitch is called the fire wall or beside the fenders

since heat caused the problem, i used cold for the fix.....there are several types of canned "FREEZE" that are used for electronic testing...i sprayed the steering wheel--twice. i think it released the weight of the steering wheel cover on the horn contacts...that or my prayers were answered......whatever the fix----currently AIN'T BROKE.....

The headlight on my 1992 Buick LaSaber will not cut off.Were are the fuse for the lights
