What you may be hearing is hum from a low voltage power module under the dash, which is activated every time you open a door. It should shut off after doors are closed, all timed devices (such as cabin lights) turn off and the key is not in the ignition. If your battery is in good condition, then either this module, the keep-alive module or something else drawing current is not shutting off the way it is supposed to. Start by checking for trouble codes (DTCs) with a good code reader.

SOURCE: overheating,eveything looks ok.

I have a 97 Cadillac Deville with a northstar engine and have replaced it twice so far, so i answer this by experience...i've noticed to my two prior engines that went bad that the normal temp should NOT EXCEED 228 (normal), the red overheating light will come on at 250 and at 260 it will beep and tell you to stop engine - idle engine and will begin to smoke (overheat).

I hope this helps you and anyone else...by the way if your asking why did i replace my engine twice is simply because my cadillac is super clean inside and out, immaculate condition.

Radio have power but no sound to car stero speaker what maybe the problem


Hi James, Im AL the owner of Big As Auto Repair.

James, Cadillac stereo systems have an amplifier and usually when there is no sound from the speakers its because either the fuse to the amp is blown OR the amp itself is bad. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

My 2001 cadillac deville keeps giving me dtc code system to lean


Anytime I get a too lean DTC I first change the fuel filter if it hasn't been changed in awhile. You'd be surprised how many times this has helped.

Good Luck with it.

1996 cadillac deville lost instruments and died while driving


This is how I fixed it, I took the plastic cover off the fuse box under the hood and found a "maxi fuse" was out and replaced it. I was suprised that a fuse could kill all electrical on the car while driving it. How scary is that?
