Q:How do I know when its time to change my transmission fluid on my 2009 elantra?

Follow the manufacturers recommendation as listed in the Owners Manual. There's quite a difference between makes, and even models within makes. For example: we have two 2008 Fords. . . . . Ford recommends a transmission service at 60,000 miles for one.not until 100,000 miles on the other. I do NOT believe in transmission flushing using a machine as offered by many quick oil change shops and chain garages: that stirs-up the fluid, contaminants and crud in the transmission but doesn't change the filter. All car makers I know of recommend having the transmission drained, lower pan removed, filter replaced and new fluid.

Q:Hey everyone.I have a modest stereo set-up in my car and I am suddenly having problems with a fuse blowing. I have an Alpine head unit, Kenwood amp, and a single 10 Alpine sub. I have had this set up in this car for about a year and a half, and had the same set up in another car for three years before that and never had any problems. Now for the past week, the fuse in the wire running from my battery to my amp keeps blowing. When I replace it, it is good for about 30 seconds, and then it blows. Any advice on where to start troubleshooting?

Start by disconnecting the wire from the amp. Replace the fuse and see if it blows. If it does, there is a short in that wire. Look for somewhere where the wire has rubbed against metal, like where it goes through or around the firewall! If that is not the problem, re-attach the amp power with the amp off! See if the fuse blows! If it doesn't, turn on the amp. What you want to do is continue testing components until you find the problem!

Q:i have got an 8 valve EFI k reg convertabile and i have only side lights working. i have no normal driving lights,no full beam and no ,rev counter,no fuel gage and no ignition lights.As soon as i put the ignition on the fuse 27 blows and the battary light comes on,can anybody out there help?

I haven't a clue what a k reg is, but the answer above is correct, you have to have a short to ground somewhere or the fuse wouldn't blow. You could have an electrical component with an internal short which is more likely than a frayed or broken wire. .

Q:after a ride i noticed my neutral light, tachometer, blinker lights and gauge, and brake light were not working anymore. im not good at electrical but i took off my gas tank and seat to follw the wires and i didnt see anything that looked like it wasnt getting contact, and i also checked my fuses. any thoughts?

Because it spent all that time in the ocean after the tsunami

Q:I pulled the fuse to the sir bags when i worked on it and put it back and now it will not go out ?

you will need to take your car to the main dealer or someone with a code reader and they will turn your warning lights out. they probably came on because you pulled the fuse or disconnected an airbag wire while the ignition was turned on the dealer will probably read the code first and inform you of a probable fault. when an electrical component on a vehicle is disconnected while the ignition is turned on the ECU will will detect a (fault) ie power failure to the individual item that has been disconnected.

Q:I was recently mudding and was stuck for quite a bit of time in mud up to my foot brake. When I went in my electric start odometer ect all worked. It even worked for a while in the mud then suddenly quit. I pulled it out and it will pull start and run fine but the 4x4 and all electrical components seems dead. I've checked the battery and it's good. I'm assuming it's a fuse or short ? But idk where to start. Thanks for all your help. Quick recap runs fine pull starts first pull but absolutely nothing electrical is working 4x4 selector lights starter nothing.

Id start with fuses, then check the wireing to make sure one didnt break or come loose

Q:Alright so my setup is a sony xm-zr1852 1000w amp and 2 12 Dual 1100w subs. One day i was driving along and started to smell a burning scent then looked back and my trunk was smoking, shortly after that the subs stopped bumping. I pull over open the trunk and there is smoke coming off the subs. I check the two 30amp fuses in my amp and they are both melted. I replaced the fuses and now the amp is in protect mode and still no bump.What's the problem?

The amp probably has a burnt component inside. I doubt that amp is meant to handle more than 60 amps, and from the looks of it, it was pulling that much for a while. You probably were clipping the signal way too much. Your subs are definetely blown.

Q:i understand you need the battery to get a car started and the spark plugs, but what else is used in a car to get it to start? i ask cause when i try to turn it on sometimes it wont start right away, the battery is fine my sparks are good, but the car still has a hard time starting up.

It's not necessary to turn it on every day, as running the car for a few minutes probably won't get to full operating temperature. But highway driving about once a week for a half hour or so is good for the engine especially in colder weather; highway driving will burn out the water condensation in the engine (which contributes to rust and water contaminating the oil). It's the stop and go city driving that puts most of the wear on the engine. Whenever the car sits for a while, I'll see milky condensation on the oil filler cap, highway driving takes care of that. Though with the $4 gas I'm not making those highway trips as much.

Q:How could this be if we are created from a single cell? Is it more the fact that we continue on from what we once were?Thank you for helping me clarify this

What do you suppose single cells are composed of -- molecules, which themselves can be disassembled into atoms. Atoms of hydrogen eons ago were part of early stars which began fusing hydrogen into helium as part of their normal process. As stars ran out of their simpler component, they began fusing the helium into heavier elements. More massive stars had more powerful forces of gravitational compression and forced fusion to higher levels. Once the fusion process reaches the production of iron, the fusion process stops putting out heat which fought to resist the forces of gravitational compression. At that moment (or instant), the star would have undergone a supernova explosion. This shock wave is so powerful that it is capable of pushing fusion to heavier materials such as gold, silver, platinum, etc. All elements from helium on, including carbon, nitrogen, oxygen, phosphorus, sulfur, and so on, were created by early stars which lived and died before the formation of our Sun. We are created from this star stuff.

Q:2.8 manual trans blows ecm b fuse in the under dash fuse box. Changed relays(2), fuel pump and ecm. It might be the fuel pump primer but I don't know where it is located.When I bypass the relay the fuel pump runs but when I try to start the engine while it's bypassed the bypass wire from the positive battery post gets red hot. The engine used to start while wired in this fashion when the fuse would fail. Now the fuse fails all the time.

You have a direct short in the ECM B circuit. When you bypass the fuse you destroy the harness, fuses are to protect the harness and the components they are connected to. They protect the ECM. The B circuit usually is the power circuit for the fuel pump, through the relay. Check the harness for continuity from the relay connector to ground from the fuel pump power supply wire I think it's tan/wht. If there is you have a short and you will need to pinpoint where. but you have probably already melted the harness together. Good luck. It might have been cheaper to hire a professional mechanic shop.
