I didn't have this problem before. All at once they stopped working

check compressure is 60 psi

The noise isnt all the time but it is getting worse.

My car stopped on me I took the battery to auto zone they said it was bad so I got a new battery but the light on the dash says battery not charging and the battery light is on but its driving now since the new battery but the light still on what does that mean

P0300 random misfire

when it stops it will turn over as if wants to start but doesnt but when it cools off its starts with no problem

I'm thinking that my air conditioning problem on my Escalade is the Low Pressure Cycling switch since it only blows air that is the same as the outside air temp. Any other suggestions are appreciated.

as far as taking the old off and putting the new one on

I took out the fuse to shut them off.

while on a battey charger, car will start if starting fluid is sprayed in the air breather, so assuming its the fuel pump, why did the battery die

It idle low all the time especially when I turn the heat or ac on

what should it cost to replace the rear differential on my 2003 Escalade?

low oil pressure

I have a 2003 Cadillac Escalade. On the way to taking my vehicle to be serviced, I began to hear a low humming noise in the center rear of the car.I had the oil changed and was told that I needed rear shocks. Considering that I was not convienced that the shocks where bad. I went and had a second opinion and was told that the shock wear ok and the vibration was due to the rear differitial and that possibly some bearings had gone bad. Needless to say I am exspecting a nice price for repairs, but I wanted a ball park figure to work with. So at least I will know if I am being ripped off. Thank you.
