Q:I need to know so I can replace it without screwing anything up. I read that in some of the newer cars the radios are connected to the headlights, heater etc. your help will be greatly appreciated.

strange idea. The radio is connected to the battery via a fuse block, to the metal chassis, to the antenna, and to the speakers. .

Q:can somebody please explain the parts marked in red on the following image

The item marked 200mA is a fuse. The 4- 47000 ohm resistors are forming voltage dividers, each pair providing a voltage of 2.5V to the 2 centre pins of that plug. The 2.5 V on each is positive with respect to the lowest plug's pin. There is unlikely to be any load on the 2.5V., it is just providing a voltage.

Q:I asked how to fix it, but was just told the same thing everyone else said, go to a mechanic and let them do it. I would like everyone to know write now that is my car, and I intend on learning everything I can about it, secondly I'm broke, and thirdly, i am a very poor grammarist.lol but seriously I would really like to know what this is.

they are a section of thinner wire(usually encased in a glass or plastic case) that fails to protect the whole circuit or component when the temperature, voltage or current drawn rises too high, hence the name thermal. fixing it is easier said than done. do you know where it is? do you know how to safely remove and replace it? can it be removed/replaced? best bet is to get (buy, beg/borrow/ steal) the service manual for your car and read that first. if you get one, it becomes a handy resource for when you need to know stuff about the car. these manuals are made either b the manufacturers or other people who atually pull a car apart and put it back together, noting instructions and taking photos, so they are relatively easy to follow.

Q:I changed all the bad fuses, then I changed the switch, then I tested the motor by hooking up a 12V battery pack, and it worked just fine up and down. What else could be the problem and how do I test it?Also, the window and the door lock mechanisms don't work on the passenger front door, even from the master control on the drivers side door.

Not exactly my area of expertise, BUT I do know that Chevy and GM vehicles in general have a history of failing electrical systems. I have heard endless stories of it and have seen hundreds of Brand new GM vehicles with burnt out head lights. I recommend just taking it to the autoshop if you've tried everything. Hope this makes you feel less alone in the issue. Best of luck.

Q:I was restarting my computer, and it started buzzing.It was coming from the mobo speaker, and now it won't turn on.On the front of it, the 3 and 4 lights are lit up.Can anyone help me?

It sounds like your speaker fuse blew. Check to see if the fuse is still intact, if it is, then you may have fried a component inside the speaker. Time for a new one in that case. If the fuse blew, you can easily get a new fuse. I had the same problem with an older set of speakers. They were really good ones with a subwoofer and all. I heard the buzz for a few days, then, Pfffft! it went out all at once. Fried components inside the speaker and had to replace the whole speaker unit.

Q:ABS dash board lights comes on. break pedal funny feeling. Took it to the garage and all the did is take out the fuse and told me not to worry about it. And everyone that I've talked to says the same thing. I drive around with my son in this truck. What is ABS and why don't people want to fix it the right way. I don't mind spending the money. I also mantian my truck to what the book says.

Take it to a Chevrolet Dealership for service. You have an issue with your anti-lock brakes. Since these other shops just pulled a fuse, mark them off your list of ever returning for future services, they are not to be trusted.

Q:I have a 1000 watt insignia amp trying to power 2 12 sony xplods but everytime i connect power to the amp the fuses blow in it. I also have a fuse by the battery that hasnt blown. Everything is right and it should work, I have gone throught it like 100 times and I cant understand why the fuses are blowing. Someone said insignia is garbage and i should just replace the amp, is this true?

probably have you tried a larger sized fuse?

Q:All the relays are replaced and all the fuses have been tested. The boo switch has also been replaced.where the hell do I begin?

Your brake lights not working is the reason it won't come out of park. Some of the newer vehicles have more than one fuse box. Mine has one under the back seat and one under the hood. The owners manual is the first place to start. Make sure ALL the fuses are good. You'll need a test light, check for power at your brake light switch, located on the brake pedal under the dash. Then check to see if you have power at the other end of the switch when the pedal is depressed. A lot of times, it is this switch that goes bad or just gets knocked around. If you have power on both sides of this switch, then you move on to the bitsy solenoid. I'd need more information to tell you where it is on your van, but try checking the brake light switch first. Good luck!

Q:At first I thought I may have blown a fuse because all of the following went out at the same timePower WindowsPower LocksPower MirrorsWindshield wipers All gauges on cluster (except engine temp, that works) Trip computerInterior lightsPower trunk latch I think that's it. headlights, blinkers, brakelights still all work. Is it possible that it is a fuse issue that caused all of those? they seem to be seperate fuses on the manual I looked at online. I've never had a fuse issue with any of my cars, so i am unfamiliar with the proccess. Just to check I pulled fuse 32, which is (Cluster, Flex fuel module, ICP logic,Passive anti-theft module). and the fuse looked fine.Anyone know what I should check out?

Sure, I'll check the power distribution schematic. Oh, that's right. You apparently didn't think it was important to list the year and engine. So I can't look it up.

Q:hiya, ive got some serious problem once ive open my pc then something sparked inside my PSU then i see that AVR turns its light off and its FUSE isbroken, the MOBO's LED light is off,but my monitor is on.and have power coz my monitor uses myPSUs power wich one is realy dead?

i think your psu is dead as the monitor takes the direct power and does not affects your psu
