Car wont carank but all electronics work

It seems your starter is in need of some service. Bring vehicle to a mechanic and ask if they can repair it. Check battery cables and clean it, sometimes build up from batt. acid and lead prevent batt. cables from connecting and delivering enough voltage for the starter to crank up. It looks green in nature but it could also be foggy white substance around batt. terminals. Other than that, your batt. must be low in voltage and needs to be recharged. Hope this helps :)

My battery on a 2012 Chrysler 300 had some kind of grayish blue build up on the red positive connection. Any idea why?

Your positive battery post has lost its seal with the battery case. This lets a small amount of gas to escape from the battery.
That gas causes the corrosion that you have seen on that terminal. You can get a battery terminal spray that coats the terminal in a waxy/ grease that will stop this happening.

My camera was left on an now it won't work. . It

The batteries drained, and the acid (chemicals) leaked out. Not a good thing. Most battery manufacturers will fix or replace devices that are damaged by leaking batteries. Check your batteries if such a warranty exists.
If not, the chemicals may have gotten inside the camera, and is preventing it from working. The chemicals in battery acid are conductive so they have changed the circuits inside the camera, that's why it no longer works. Power is going places it shouldn't - and not getting to places it should.
Battery acid will burn skin, eyes and clothing - be careful and wash hands thoroughly! You can neutralize battery acid with a 1 part baking soda to 4 or 5 parts water solution. Dip a q-tip into it and dab on acid coated parts as a last resort. I don't expect you'll have much luck if the battery company won't replace it for you. Good luck!

When i open the hood on my 1999 jetta it smells of acid and their is white powdered acid all around the positive pole

I would replace the battery, but if you are unable to I would go to a parts store and pick up some terminal cleaner. That would take care of the acid build up giving you a better connection.

Car won't start. There's no clicking sound but auto seat belts and some dash lights come on dimly.

Check the battery charge and also check that the battery terminals and clamps are clean and free of corrosion and acid residue build-up. If there are signs of acid or build-up, clean with boiling water only. Do not use baking soda or bicarb!

My car want start battery is fully charged. But the immobilizer light on the instrument panel stays on?

Having a full charged battery won't just solve the promblem. You might want to check with the battery terminal connection on the postive+ and negative-, It might be corroded, grease, or acid build up, so check for thse signs, also it could be that clamps are not fully tighten. You still can get power to the car from the baterry which in this case is leads to the immoblizer lights on the dash boards to stay on, but the terminal are corroded with acid, grease, or just from dirt, and with these element in presence, the battery is not fully ground. The engine needs a specific amount of amplitude from the battery for the engine to crank. A kia sorento v6 engine needs alot of cranking amp. So my solution is, check the battery connection terminal on the battery and the cable (positive and negative connections) de-tach the cable connections, clean the connection cables which are the adapter to the battery, and the battery terminals, with a toothbrush or high grit sandpaper until dirt, acid build up, grease are gone, and reinstall the cables. See if this will help.

Hi, this normally indicates high amperage draw. If your check engine light is not on and all seems to be working fine, take a good look at this cable for acid build-up. Dirty connection will cause this. You may have acid build-up inside the insulation on this cable you can't see, as it will crawl up the cable to its other connection point, ground or starter solenoid. Check the condition of the battery also. If you run it by a Auto-Zone parts store, they can for no charge run a load check on the battery for free to check its values. Theses are the things to look at. Keep me posted.

The cables on my battery keep getting all junked

Well, the battery itself is the first culprit. Check and see if you have a battery that is leaking. Excess acid will cause the build up. If you have the battery waranteed, you can get it replaced and it will be pro rated.

The most likely cause of this is a faulty exhuast recirculation system.It is used to cool the combustion process preventing the formation of nitrous oxide emissions. The main building block of acidic rain.Use your emission diagram and locate the EGR valve.You will need specialized equipment to check it. Other than taking it off and checking for blocked passages from carbon build up there is little you can do yourself.
