Question about 2002 Cadillac Deville
My 02 DeVille didnt start last week. Bought a new battery. Started and ran fine for 1 week. This morning it wouldnt even turn over. Only the dome lights came on. What is is it? Starter? Alternator?
Well first off, check the glove box light blub, make sure it shuts off when you close the door, check it by pressing the switch with your finger to make sure it shuts off, also check under the hood for the light there if there is one, pull the bulb, and the same thing for any bulb in the trunk, then check again after a day to see if the battery dies, if it is dying while the vehicle is not running then it is the battery, if it is dying after it is running then it is the alt. you can check that also tho with a multimeter set to the DC volts setting, place the black end <the ground to any grounded area> and the red end <the hot lead to the back of the alt. > it should be reading higher then 12 volts, normally should be a higher reading then 12 volts... if you are getting a lower reading or just 12 volts then the alt. is bad and needs to be replaced...hope this helps you out...
