There is no sound from my car stereo...

Try to tighten the battery terminals, make sure the ground wire has engine/body contact.

Starter motor solenoid faulty or starter motor jammed on!

Sounds like you spiked/damaged the aftermarket alarm module.

What are you boosting the fuse box for,? Are you trying to blow the vehicle up? Where did you learn to boost a car? The car that your useing to boost the car hook up one cable at a time to the batterys of both vehicles The car your useing for boosting hook up the ground to the battery first ,Then on the car that your boosting hook the ground cable to a the engine some where , To ground it, Not buy the belts or moving parts , Then hook up the positive to the postive terminal of battery in the car you are useing to boost the other car ,Hook up positive cable to positive terminal on car that you are trying to get started, If you don,t no what your doing get help from some body that has done it before, One wrong move you can (Screw) Up the computer in the car, End you might of done that (Allready)

get an adaptor kit for the stereo wiring. it will plug directly into the factory harness and vertually eliminate cross-wiring.

look at your remote (if you have one), then check the fuse in the fuse box

My 2007 dodge durango has a light on in the dash what is it and what do I need to do it looks like a horse shoe with a ! in the middle

The 2005 Durango has a notorious issue with the exhaust manifold blowing out
it is a $10-$15 fix if you have someone to replace it.

when you first start it up it sounds loud like the HEMI but then it settles down, also the gas mileage and the power have been reduced as well. best bet is to buy the part and a chiltons manual. $15 bucks and a case of beer later you should be good to go. Midas muffler shop can confirm the exhaust leak as can any mechanic worth a **** and they SHOULD NOT CHARGE YOU!!!

you need to replace the altanator

sounds like the altenator or voltage regulator
