Question about 1994 Buick LeSabre

1 Answer

We bought a 1994 buick LeSabre and the horn, trunk button and power lock for the doors won't work. We have checked all the fuses and they are all working. We also checked the wiring from the horn and doors and all appear to be getting electricity. What else should we check?

1994 buick lesabre trunk lock-how can I open the trunk without using a key. the key doesn't work although it open the doors to the car. is there a release button somewhere? we do not have the r


If it has the electric trunk release, the button could be in the glove box.
Otherwise you may have to remove the back seat to gain entry to the trunk.

Windows, side mirrors and door locks suddenly stopped working on 2002 Buick Lesabre Limited


The first thing to do would be to hook up a factory or professional type scan tool an check for DTC'S - diagnostic trouble code's . This vehicle has very complex electronic's. Serial data communication network,class2 data bus . There are electronic modules inside the door's that control the lock's ,power window's , power mirror's . Your best bet ,take it to a qualified repair shop . Not a fuse problem , driver an passenger door module each have thier own power supply. Two circuit breakers ,PWR/WDO circuit breaker 30 amp. You could check DRVMDL 10amp fuse ,located in the rear fuse box , PASSMDL 10amp fuse rear fuse box , RRDR/MDL 10 amp fuse rear fuse box . Rear fuse box is under the back seat . None of the window's , lock's etc.. work from any door switch ?

Horn randomly honks(very annoying while your trying to sleep) HELP!


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.

1989 buick lesabre horn won't blow .check relay's on passenger and driver side under hood .push horn button hear quicking in fuse box under dash on passenger side.help....


possible horn itself is faulty and needs replacing. you will need to locate where the horn is and apply power to the horn from the battery. if the horn sounds then you know that it is a broken wire th=o the horn

Horn won't work on a 1994 buick lesabre and i don't have a fuse diagram


if the horn doesn't work it is most likely the rotating ribbon circuit contract under the steering wheel called the "clock spring contact", the circuit runs along a plastic ribbon and that breaks from all the turing of the steering wheel over the years, then the horn button is no longer connected to the horn circuit.

Are the power door locks, power trunk locks and interior courtesy lights on a 1994 Buick LeSabre controlled by the same fuse? Mine don't work, even with the remote control on the key chain. Anyone know...


Obviously you'll want to check the fuses first as that's the easiest, but i think you may find that the problem is a bad common ground. Pull up the carpet a little near the drivers door opening and you should find a large group of ground wires. That area is a susceptible to water entry and with water comes corrosion. If you find it corroded clean it up as best as possible with a wire brush and reconnect everything and put some dielectric grease on the area.

95 buick lasabre horn problem


Ever find out what to do with this? I'm running into the same problem and see multiple refrences to it, but not much for follow up on what fixed it. I pulled the fuse for mine, but it kills the trunk release and automatic locks...so I'm not a big fan of that.
