1994 S10 Blazer electrical problem?

Question

There is a short somewhere when i apply the brake and i don't know what it is. I push on the brake and the radio shuts off and the gauges go haywire. All the gauges drop and the speedometer reads a lot faster than what i am actually doing. This morning, i was sitting at a stop light, waiting to go, and it happened again, and the car sounded like it was going to shut off, but didn't stop all the way. About a mile or mile and a half up the road, it did it again and shut off all the way. Does anyone have any idea what the problem might be?

Answer 1

Sounds as though you've a short somewhere in the dashboard wiring. Get up under the steering wheel and inspect the wiring bundled up there for obvious signs of damage.

You can also try pulling 1 fuse at a time and seeing if you can re-create the problem. When the problem goes away with a fuse pulled, you've found your suspect circuit.

Answer 2

each 3 months you replace your exhaust!??!?! Theres no way this may be a variety of yours, simply by fact thats insane. What you ought to do, is flush your engine. What you do is drain the oil thoroughly, then replace it with a kerosene (aka, engine air purifier). mild oil mixture, then commence your vehicle breifly, then close it off, drain the kerosene, fill back with a mild oil, run it for slightly longer, then finally fill it with despite the fact that weight of oil you utilize. this might clean the carbon deposits. next, stop using low-value gas. I cant even think of a condition that a cat and muffler might desire to get replaced each 3 months. How plenty oil does your blazer burn a month? Is it a quart an afternoon... an hour? Thats insane, your muffler guy is screwing you huge time. Take it someplace else, and have them replace the cat with a straightpipe or severe flow cat, which will resolve the subject of it being clogged (if thats even a possibility after changing it much less then 3 months in the past). so which you replaced the plugs and wires, did you replace the ignitor besides? in case you have new plugs and wires yet a bad ignitor, you havent achieved something. jointly as your at it, see in case you have a gas clear out in place.I mean to clog a cat each 3 months, you have to be burning rubbish on your cylinders. And after that, see in case you have an air clear out on the vehicle!

Answer 3

Obviously, it's a problem with the brake light circuit...must be an intermittent short in the switch or one of the wires going to the brake lights. Wirediagram.com will have schematics on which color wires go to the lights and anything else.

Answer 4

Look for a bad ground wire. If the circuit cannot conduct to ground you will see ghost problems like this.
