Question about 1999 Buick Regal

1 Answer

Since you sound like you know what you're talking about I figured I'd message you directly :)

Okay I kind of understand what what you're saying I think. I'll wire the black wire from the car into the black wire of the light I bought and then run the red wire from the other end of the light to some place to ground it on the frame? I don't have a test light, I actually don't even know what that is, so I'm just doing it with the light I purchased. I'm not so sure that the wires with lines on them are tied in for trailer lighting however, because these are the wires that were originally tied directly into the sockets that I put my turn signal bulbs into (not in a wiring harness for trailer lights which I've seen on other vehicles before). When I disassembled it today I was surprised to see that, coming from the one harness there were three wires going to the turn signal bulb socket and only two wires on the light I bought. With the wiring configuration I explained in my previous where my interior lights dimmed in sync with the blinker I was able to get both a blinker and brake light response out of it (although I don't think I tested both of them at the same time which is what I think you're getting at with the double element bulb thing). Would you expect there to be three wires on the aftermarket turn signal I bought if it were a double-element bulb? I've never delt with this before, so I just picked up a generic rear turn signal at Wal-Mart the other day. If I need some other sort of light that you can think of please let me know and I'd be able to go purchase it ASAP. Thanks for your help by the way

    It says that the red wire goes to the gurn signal and the black wire goes to the brake. I rigged it up like that and both of them work individually, but when I have the blinker on and then apply the brake it doesn't do both (i.e. I assume this is what a double-element bulb would be needed for). The only thing is that my car has an extra black wire coming out of it. I did green to red and black to brown as the turn signal instructions said, but the wiring harness going to my original bulb had a black wire also. As of now I'm assuming my setup is just fine since both turn and brake work, but the only "problem" is that the turn signal blinks about twice as fast (which normally happens to indicate that one of my bulbs is out). So I'm fine sticking witht he current setup temporarily, but if theres a way to fix that I'd be interested...

If it is for a turn signal and there are 3 wires, then it will require a double element bulb if it did not come with one, I think the 1140A comes to mind. One for the brakelight and one for the turn signal. a test light is just a probe with a small 12 volt light in it and an alligator clip for attaching to a ground point. when you find 12 volt with the sharp probe for digging into wires without having to strip them. with turn signal on the light should blink on the test light, since it is temporary it would not matter which one goes on as long as it is on and working the kit should have come with a clamp on wire splice, if you had the test light you could make sure which wire was which and simply tap into that power line. About the 3 wires one for turn signal, one for brakelight and one for ground, it should have at least come with an instruction sheet to indicate which wire was ground? Hope this helps, if not I will be here to help.

No low beam headlights hi beam okay fuses 11, 16 okay relay hdlp lo/hid okay bulbs seem okay

Did you check low beam fuses for voltage, with headlamps on lo beam? Use a testlite to check for voltage. In the diagram you see the lo/hid relay, correct? I'm not saying the relay is faulty, you need to check voltage and ground. The bcm and dimmer switch are involved, I don't know if check for headlamp/lighting trouble codes will help? Don't replace anything unless your testing points in the direction.

What To Expect From An Online Car Expert

If you are reading this it is because you are probably looking online for an answer to your car questions. First, we need to establish that there are only two kinds of automobiles that have ever been manufactured in the entire world...the kind that are broken, and the kind that are going to break. Everyone that has ever owned an automobile has experienced some type of trouble with his or her car.

The modern automobile is probably the single most sophisticated and complex thing available to the general public. To understand them, you need to not only understand the basics of how mechanical things work, but you must also understand a considerable amount of computer technology, electronics, advanced electrical diagnosis and repair, hydraulics, upholstery, metal and plastic fabrication or repair, welding and several other things. You have to be able to figure out what is causing a noise or a vibration. You must have a working knowledge of how all of the many complex systems in an automobile works. You also have to understand that there are systems within the major systems and how to eliminate possible causes of a problem in a timely and accurate manner. (Poor time + mistakes = money lost!)

Car owners get really upset when they have car problems and they always want them to go away. They never want to have to pay to get their car fixed. This is understandable. Owning a car is expensive enough with car payments, insurance, licensing fees, fuel and scheduled maintenance. So here they are paying the big bucks for transportation so they can get to work and try to earn a decent living, and the [blankety-blank] thing decides that it is time to break down and eat up more of their money! Welcome to the wonderful world of vehicle ownership!

Then there is the problem with people calling themselves car "experts". Some actually are, some wish they were, and some don't know the difference. (These are the REALLY dangerous ones!) My experience has shown me that this happens in the "cyber world" even more than in the "real world". The only supervision for a so-called "expert" in the cyber world (myself included) is the person asking the question. The sad part about that scenario is that the reason the question is being asked in the first place is because the asker doesn't know the answer. (Is that like grading on a curve?) There is no shop manager to censor or validate what the person is saying to the "customer". In most online auto forums, as long as there is no abusive language involved, the "expert" can say pretty much anything they want to the "asker". Please note that I am NOT exempting myself...even this article is an example of one of those "anythings"!

The main difference is experience and intention. There are those that strive to give just as good an answer to the "free" questions as they do the "pay" questions. These are the guys that are really interested in helping people.
There are several of them on this site (if you can find them).

Here's what you can expect:

As a general rule, the online "experts" are not very likely to LIE to you...not even the bad ones. You can pretty well expect that they believe that what they are telling you is the truth. There is no reason to lie, so it is probably not going to happen unless someone is just getting a kick out of being a joker.

2. You can expect the expert to answer your question as you asked it. The expert may not fully understand what you are talking about. If you did not ask a complete, detailed question, do not expect a complete, detailed answer.
Many of the experts will have to ask questions of you to get a better understanding of your situation. Do not expect them to automatically understand what you are saying if you didn't say it. Also, do not expect them to know exactly what is wrong with your car based on your original question. Depending on how your question is worded and how the expert read or understood it, he or she might know, and then again maybe not. Be ready to work with them.

3. You can expect an expert to ask you to give him vehicle information if you did not include it in your question. It is necessary to know the year, make, model, engine size and (possibly) what type of transmission your vehicle is equipped with. Without this information, it is impossible to look up accurate repair information for your vehicle.

4. You can expect an expert with the VERY BEST credentials to be an EXPERT, not a mind-reader or miracle worker. Even experts have to perform testing and diagnosis to find the cause of a problem. If an expert is telling you that some kind of test needs to be done before he or she can answer your question, this does not make them incompetent. This simply means that they want to help you find the cause of your problem and get it repaired without wasting your money by "guessing".

5. You can expect an expert to ask YOU to do some testing and diagnostics and report back to him or her. online expert does not have access to the vehicle. It is hard enough to figure out what is wrong with a car when you can see it, feel it, and perform the tests yourself. This means that YOU have to do it. Don't expect an expert to automatically tell you exactly what is causing your problem without you having to do anything or provide feedback to the expert. In most cases, this is just simply not going to happen. Even the BEST of the BEST experts cannot fix most car problems without some type of testing being performed.

6. You can expect an online expert to do the best that they know how to do. Experts are not superhuman. Some are just better or more experienced than others. All but a very few of them have the very best intentions - even if they seem to give you an answer that has little or nothing to do with the problem you are having. It may be because of a misunderstanding of the question, or it could be that the expert does not really know the answer, but is trying to help anyway. It is human nature to want to help.

With all of that said:
Welcome to FixYa! I hope I can help you.

Sorry, my US database doesn't list a 6 cylinder for this vehicle. If it's a 4 cylinder, now were talking. If I understand you correctly, maybe the fuel injector is faulty? I don't know what kind of testing you have done?

2007 gmc electric towing brake code on

It sounds like the brakes need some work done. I would suggest talking to a mechanic or a tow company to see if they can help you understand it. Whatever the problem is, I would definitely suggest getting it figured out sooner rather than later. The last thing you need is to have it cause a problem when you're in the middle of towing another vehicle.

2002 kia spectra 4 door

I would say it sounds a bit high. A radiator flush and fill, which I think is what you are talking about, should be about $100. If it is a normal brake job, I only see it costing about $75 for the rear only. And a belt replacement should only be about $20-30. Now I do understand this is a shop so they have overhead that will cause prices to be a bit higher, but this sounds a bit too high. It would be better to know the exact work being performed. Some places will take advantage of women as well as men who do not know much about vehicles.

I meant it quit pulling i cut the car off waited about 5 r 10 seconds granked it back up in neutral put back in drive started pulling like a new 1 4 about 5 miles same thing over and over can u explai

okay, let us see if we can figure this out.
Its sounds like you were driving and the engine stopped working or engine kept running but transmission stopped pulling the car? and when you shut it down for a while then restarted car the transmission worked good for about 5miles and then stopped pulling. is this correct? if it is then check the transmission fluid and make sure it is full, to check fluid car must be on level ground and engine running and shiftter in park.

If the fluid is full then i would say you have ****** problems and should have it looked at, before it gets worse. good day.

The transmission does not know what gear or how fast its going so it communicates to the powertrain it tell it I dont know what Im doing so it activates the traction control and say keep me safe the traction control say okay Ill get disable, then the transmission control tell the powertrain I could be burning up or slipping.
