Air bags and the air bag system need to be serviced by an approved auto shop. The light will come on when there is a problem with either an air bag or the bumper sensors which will trigger them in an accident. You should be able to determine the specific problem by checking the error codes with a code reader.
Adding a can of refrigerant might temporarily solve the problem.
A car of that vintage could have wide variety of problems. Since you have purchased the refrigerant, you should have a friend that has done this before show you how to do it. Don't be surprised if that does not solve the problem. I would recommend that you return the stop leak, and refrigerant, save your money and hire a professional to fix it. Find a grey haired auto air conditioning mechanic that is familiar with that year and model car. They should be able to determine quickly if it just low refrigerant or something more expensive.
If the key is not coming out of the switch, it may be off, but you haven't turned it far enough back that final click to remove the key. Some have a button you have to depress to get the key switch to turn back that final click. That's it.
To be sure it isn't seized up try to turn the engine over by hand ! Get a socket that fits the crankshaft bolt . 1/2 drive an a breaker bar , you can buy them at a parts store . Me i prefer craftsman . If it spinnes it's not seized , then you need to look at the electrical part of . Do you know how to test automotive electrical circuits ? Voltage drop testing , how to use a DVOM - digital volt ohm meter ? Do you know the componets in the starting circuit ? Starter of course , PNP - park neutral position switch , starter relay , Heavy gage battery cable to the starter , control wire to the S terminal on the starter solenoid . How to voltage drop test starter motor circuit
yes. You just need an honest, qualified mechanic. I'm not saying your last mechanic was not qualified, but any mechanic should know how to search and test for an unintended drain. Sounds like that is what you have.
Go on youtube and watch videos of "unintended, or parasitic drains"-there are hundreds of them. Any mechanic with a good multi-meter should be able to find it pretty quick-within an hour or two.
I wouldn't worry about the AC-your car is too old for it-too easy to have problems with a car that old, although if you have enough money, you can do anything. Just saying it would be expensive. The window problem is not an expensive fix, probably needs a new window motor. yours probably has worn brushes. The rear defroster is easy to troubleshoot with a multi-meter. Keep at it and you will have a good car.
The click is the solenoid not getting enough power to energise the starter and engage the pinion gear. Either the battery is weak or the connections going in the starter circuit have excessive resistance and need to be tightened/cleaned.
Your question is inconsistent with the fuse panel you are showing in the picture. The only place you will find the ignition fuses (there are two of them) is on the driver side, under the hood electrical center. They are 40 amp fuses in position/location numbers 3 and 4.
If the service engine light is on, this is in a way a good thing. This means that your vehicles computer has detected a problem and the computer has stored this information for you. Now the trick is how to get that information from an older system like you have (they changed the system in late 1996). You need to find the data link connector which should be under the dash on the drivers side of the vehicle and I believe yours (don't quote me on this) is on the right side of the steering column by the brake pedal or even mounted on the bottom of the dash (same area though). Below is a picture of what this data link plug looks like. Now have a peice of paper and a pen also a paper clip (one of the bigger ones are better. Now take that paper clip and kind of bend it into a "U" and insert one end into the letter "A" spot on the plug and the other end in the "B" spot on the data link plug. After you "jump" A and B turn your ignition switch to the on position without starting the vehicle and look at your check engine light.. Here is where the pen and paper come in. The check engine light should start blinking. The begining or starting blinks should goes as "blink" (one blink) - Pause - and the "blink blink" (2 blinks). This is a code 12. A code 12 means the system is working. It will blink a code 12 three times. After the code 12 there will be a litttle longer pause and then another code(s) should start. this is where the counting comes in. so after the code 12 and the pause, if it blinks 4 times - pause and then 2 times, this is a code 42 ( am using a code 42 just as an example). It will blink the code 42 (or whatever code) 3 times and then move on to the next code. There may only be one code but if there is more they will go in order. When it goes back to a code 12, the diagnostic is complete. Write down what codes you retrieved and these codes will lead you to the direction of the problem and there are testing procedures that go with each code. Until I get those codes, I am unable to help you any further. Once you get code(s) you can reply/comment here what they are or feel free to email me directly at firstname.lastname@example.org with your vehicle information (make, model, year and engine size) and I will be happy to try and help you diagnose what the problem is such as a sensor or whatever along with tesing procedures so you're not just replacing parts that are not needed. I know this was a long explanation but it's the only thing to be done at this point. Hope I was able to explain it to you so you understand and I was able to help.
The two upper motor mounts, between engine and the bar running across the top of the radiator, must be disconnected at the engine end and the engine rotated forward, so that the rear plugs can be worked on. On a Chevy, there is a second hole in one of the mounts (dog-bone mount) that can be used to hold the engine forward. I'm not sure if the Oldsmobile has this type of mount or not.
