View 3 RepliesMy horns aren't working. I'm getting power at the horn fuse, but no power at the horn connectors. Where is the horn relay located? Is it in the fusebox under the hood? There are many relays, but none of them labeled "horn".
View 7 RepliesMy wife's 2007 Buick Lucerne wouldn't start the other day after sitting maybe 20 minutes with the headlights on. She had to call AAA for a jump start. It starts fine now. I took it to an autoparts store, the battery shows 90% life left. Brought it home, charged in 10 minutes using my car charger. My question is, what could cause the car not to start so easily? I am skeptical the battery was the culprit. How can I check the alternator, etc? Any other thoughts?
View 9 RepliesMy horn isn't working. The under-dash fuse is OK and was going to check the horn relay, but can't figure out which one it is despite numerous FTE and Google searches. I pulled the cover on 2 power distribution boxes under the hood, driver's side. One box has 2 relays. The other has 4. Which one controls the horn?
Then...how do I test it to see if it's good/bad?
My horn suddenly stays on when I hit the horn and it doesn't beep when I lock the door with the key fob. Only way to turn it off is to shut off the truck. I thought it may be a faulty horn relay. I've asked many mechanics where the horn relay is located and every one gives a different answer. Under the hood, in the driver side kick panel, under the dash, near the horn itself. Where the horn relay is located on a 2004 F-150....
View 1 RepliesAttempting to debug the Horn not working on my 2003 Ford F450, The fuse is good (shown as #37 15 amps) so next I would like to check the Horn relay.
View 5 RepliesJust noticed I have no more horn... I had car alarm issues for a while and the alarm would sound all day in the parking garage while I was at work (was keeping the car unlocked at home...) Finally fixed the hood pin.
Going back to the horn, the horn fuse was burned in the hood relay box, and when I replaced it and tried the horn again, it burned again... Where to start? Do I go for new relays, new horns, new wiring or all of the above...
We have a 2008 Buick Lucerne. Now that the weather has become humid, we have been using the air conditioner more. We noticed that the carpet was wet on the rear passenger floor. Shortly after that, we noticed it on the driver rear floor. The dealer repair guys are puzzled and say it can't be the air conditioner as it would get the front passenger floor wet and not the back. They blamed on a luggage rack or sun roof (which we do not have!) or on the rain or car wash. We haven't been through the car wash and it hasn't rained here in over 3 weeks. What would cause this to occur and how do we fix it?
View 4 RepliesI've seen posts about this problem online, but no one has listed a good fix. There seem to be LOTS of '06 Lucernes with back doors that won't open. It is not a child door lock issue as the customer has no kids needing such protection, and the door should open from the outside anyway.
I need to remove the inner door panel, but can't figure out how to do that with the door closed. Once the door panel is off, I can probably see what's going on inside, and maybe fix it.
Installed new compressor, condenser, drier... Local shop wanted to charge $140 just to evac. Bought vacuum pump and gauges/hoses. Evaced the system, held -30 for 45 minutes. Started car and proceeded to add freon... Compressor would not engage. Low pressure showed 90lbs but would not take any more and compressor wouldn't engage...
View 7 RepliesI have a 2006 Buick Lucerne. The wheels were losing chrome and were oxidizing. I just bought some new "Koenig Unknown" wheels for it. I took it to the local shop to have the new wheels put on And one of the tires had some bad scuffing on the sidewall. The mechanic said it was too much damage on the tire and that he could not mount it on the new rim. So, I took it home and did it myself.
The duct tape that I used under on the flat bar was not sufficient and I ended up putting some rather deep nicks on the edge of the new rim. Though you cannot see it them unless you look very close, I know that these digs can be sources of corrosion. The lip of the rims are a polished mirror-like aluminum finish. I am sure they have some clearcoat on them and that is what I have damaged. How I can fix them to prevent any corrosion from happening.
I just put new rear air shocks on my Buick Lucerne. I noticed the back in my car bounced more than once when I tested them. After starting the car I hear the air compressor run for about five seconds. This seems to have no effect on my new shocks. The old shocks had holes in the bladder. What tests can I perform to figure out what's wrong?
View 8 Replies2006 Buick Lucerne... I have been experiencing this for about 12 months… But now I have new tires that have been balanced twice by two separate shops. I'm still getting a wobble from the right front at about 65 miles an hour. The original tire on the right front has outside wear about half way around the tire. It seems very strange… Half of the outside of the tire is down to the cord the other half has some tread remaining… It's like something is shaking it up and down…
View 11 RepliesMy wife's 2007 Buick Lucerne's directional signal is acting odd... When you turn it to the left-hand blinker, the pace is not the normal factory pace. After two or three cycle it then starts blinking on and off VERY quickly, like those blinkers you see on junkers periodically. The right blinker is normal pace as are the hazards lights. I am looking for potential causes before I bring it in for repair. I can't say anything trigger it, other than I noticed it after a car wash. Electrical problems are not my thing.
View 5 RepliesI bought a one-owner, 50,000 mile Buick Lucerne in February. Yesterday I heard a squeaking noise from the steering wheel/column and it is there today. Does this mean I need to lubricate or replace the lower seal on the steering shaft?
View 2 RepliesI cant find the location of the Turn signal relay, its not in the Relay box under the hood nor is it on the fuse panel under the dash, i'm planning on installing LED blinkers and i want to switch out the relay to a LED compatible one, where it is?
2008 Santa Fe GLS ....
My Dad left me his 2006 Buick Lacrosse. Beautiful car. But I had the problems with the low beams not working and had to use the high beams to get home. My son replaced the relay for me and it worked fine....for awhile. Then I had to have the relay replaced again (the car parts place) ... it worked for a few months, then it FRIED ! Smoke was pouring out from my hood and the whole relay box melted. Now my car won't work at all ! I cannot afford to take it to the dealer. I would like to get it fixed so I can sell it and get a car easier to fix.
View 1 RepliesWhere is the relay box for turn and hazard signals in 98 Buick LeSabre custom? my hazards ans signals don't work switched fuses but didn't work. Where the box is I've never owned a Buick til now. there isn't one under the hood just the main on the driver's side.
View 1 RepliesMy wife had the misfortune of the horn sounding each time the signal was turned on. Solved problem by not using signal... However, the horn still went off after the truck had been turned off for an extended period of time (long enough for her to leave and not hear the horn until returning a couple hours later). She was able to stop the horn by placing the vehicle in neutral (manual transmission). I have not been able to reproduce the problem. I thought it may be the "relay integration", but after removing this from the vehicle the signal does not work, but the horn still works. Is there a relay, switch, etc. that controls both of these devices?
View 1 RepliesI'm trying to figure out where the horn is. Since mine has graciously decided to not work!
