2000 Chevy Blazer won't start after horn and lights flashing out of control

I am not sure if I hit something with my knee under steering wheel, but my car's horn started beeping and wouldn't go off, turned car on and off and horn stopped. Closed door then the lights started flashing. Got back in car and tried to turn it on, now it won't start. When I get out of the car and touch it at all, the horn and lights start up again even though it won't crank over. ?????

SOURCE: I have a piece missing

While I applaud your ingenuity, when something doesn't work, you do have to learn to back off and get the right parts. It is never a good Idea to Jerry Rig a Jerry Rig!

SOURCE: 98 Chevy blazer won't start up but will crank ,,

Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.

Pull steering wheel without steering wheel puller

To do this you need two ball pin hammers. First you need to remove the horn cover and then you need to loosen the large nut that tightens onto the steering column. Loose the large nut to the top of the shaft put your knees under the steering wheel and push upward as you put one hammer over the large nut and then hit that one with the second one and it should pop off the spline it is pressed to. Be sure you are wearing safety glasses as you do this in case the hammer chips a piece off.

I have a 2005 Nissan Altima and my horn don't work

you may have a problem with the clock spring or spiral cable as nissan calles it. it is a part of the air bag system and also horn signal runs into and out of it.if that part is bad, your air bag light will flash and your horn will not work. has anyone been doing any repairs inside of the steering wheel?? it may just be unpluged. if you are going to tackle this your self to look inside of the steering wheel, make sure you disconnect the battery for at least 3 minutes, befor you start playing with the air bag. you dont want to blow it up.

1985 chevy blazer steering wheel removel

Remove the horn button, it should pop off unless you have the deluxe wheel in which case it is held on with 2 Philips screws on the back of the wheel. There is a large nut that has to come off as well as some bits and pieces for the horn. PAY close attention to how these pieces come apart or your horn won't work when you reassemble it. Attach the steering wheel puller and remove the wheel. It helps to give the bolt on the puller a rap with a hammer as you tighten it. Don't bother to try to do this without the puller... it don't work.

With the wheel out of the way, you will see a plate with grooves in the edge of it. This is the locking plate. There is a special tool to remove this but you probably won't be able to rent it. Try to borrow it if you can. If not, it can be removed without the tool. BE WARNED that THIS PLATE CAN HURT YOU as in break teeth or a nose. It is spring loaded with a very heavy spring. To remove it get a piece of boomstick or bar about 16 inch long. Enough so you can use your shoulder to push down on it and hold it while you pry the lock ring off the center shaft. Then ease the plate up until you feel it break contact with the spring. then remove it and the spring. Don't bother trying to put it back together without the spring. You'll just have to take it back apart and put the spring in. Hope this helps.

How replace turn signal switch 2000 chevy blazer?

Since the 2000 chevy blazer is equipped with SRS (Saftey Restraint System), ie: Airbags, which is located in the steering wheel. In order to replace the turn signal switch you must remove the steering wheel. Therefore I would only highly advise you to take it to a dealer to have this done.
