Question about 1998 Buick LeSabre

1 Answer

My 1998 LeSabre has the intermittent horn problem which is definitely temperature related. It likes to go off about 3 AM on a below 32 F evening and nobody in or near the vehicle. It occasionally starts constantly blowing while driving but a tap on the wheel pad srops it. Is this an expensive fix?. It's obviously in the horn pad.

You are correct in your diagnosis,unfortunally it is an expensive fix because you are dealing with the air bag assembly. This was a issue on several Gm cars, when they were under warrenty we would just replace the whole thing,but having to pay for it that's a whole different story.Your only other option is to put a remote horn switch on the side of the steering column and bypass the horn pad /air bag

Where is the fuse controlling the horn on 1998 Buick lesabre

first, an owner should always have a service manual
or an operators manual at a minimum
the horn is fuse #3 on page 6-58
there is also probably a horn relay to consider.

How can I remove the horn relay from a 1995 buick lesabre

I believe it is the fourth relay from the left passenger side in the engine compartment against the firewall. I am assuming your horn intermittently goes off by itself. It's a interior heat related issue. The horn pad cover on the steering wheel has a membrane layer. It's basically a switch that has one wire that goes to the horn relay to activate the horn. The Buick GM logo embossed on this plastic cover is where I found it most sensitive to any light touch. Unhook the battery. If you carefully cut the right edge of the the steering wheel horn pad and carefully pry it out a little, it will fix this issue and still be able to use the horn. It's another GM defect. I hope this helps! Let me know.

Horn keeps goin off by itself. would likento know where horn relay is located

I do not have a listing for some reason for the relay itself but would pull the fuse anyhow so there is no power to that circuit anyway. The fuse you are looking for will be in the passenger side fuse comprtment (location instructions below). The fuse you want to ppull for the horns will be the number 3 fuse (see picture of fuse layout below). I hope this helps until you get the short fixed and good luck.clifford224_522.gifclifford224_523.gif

1998 Buick LeSabre horn does not work

First thing to check would be a fuse. After that I would check power and ground with a test light at the horn, when the horn is being applied, if you have power and ground when the horn is being applied, you have a bad horn. If you are missing power or ground, there is an electrical problem to investigate.

Horn honks by itself

This is a common problem with GM vehicles in that year range. The horn switch (buttons) in the steering wheel pad get stuck closed. The switches are embedded in the air bag assembly and would be difficult to replace. A temporary fix to stop the horn is to remove fuse #3 in the relay center which is located in the bottom of the dash on the passenger side, the plastic cover has to be removed for access. DO NOT only disconnect the wires from the horns as the relay switch that controls the circuit will remain powered constantly and will kill your battery. To restore horn function there are aftermarket horn button kits available at most auto parts stores.

If this info is helpful please give me a favorable rating.

Horn doesn't work on 1998 Buick LeSabre. Mechanic gets it going for a few days, then nothing. Wants to install push button horn but husband is balking. Says he'd never be able to sell it that way. Any...

He's correct. I don't want a butchered vehicle, with a horn button on it somewhere.
I hope you don't consider that shop or at least that mechanic a professional.
You only have a horn button,relay and a horn. IF,you are a knowledgeable car repair person,you test,then the results, will tell you which one is bad. Easy job.
In some cases a vehicle may have a clock spring, under the steering wheel that goes bad,(way too technical for your guy)
Must say any shop,even those that are questionable at best,could properly repair that issue,just not your guy,loose him.
