Replying to: etbartley (Jul 24, 2007 10:29 pm) If this problem continues, I would guess the problem being the battery cables, the positive or negative. Corrision has probly gotten inside the rubber and eaten almost thru one or both. A common problem on Cadillacs. The positive cable is somewhat complicated and expensive to replace completely. It will go from the battery to the starter, which on a Northstar is inside the intake manifold. Intake must be loosened and lifted to get to the end of the positive cable. |

I was given a 1986 caddie (DeVille or Devil of a time) and among other problems its gas gauge does not work. The display on the heater or any of the other digital displays will not read out. I am having a new problem now with the battery. I goes dead very couple of days. I can hear something clicking and checked under the hood. It is definitely a electrical component. It is right behind the battery and nothing in the manuals suggest what it might be. I am getting gas fumes when I start it. It is running too rich and will blow a little black smoke sometimes. I am sure there is more to the problems with this thing. I am trying to fix it one thing at a time. I replaced the fuel filter, battery, spark plugs, distrubuter cap and roter. It does run, but runs out of gas a lot. I have trouble with the cars idle speed. I can get it right and in a few days it is not running right again. Any suggestions on getting the battery not to run down or how to get the gas gauge working again????

Every now and then, like months apart, the interior lights, cigarette lighters, and trunk light stop working. We have checked all the fuses and they are all fine..but cant find out why I suddenly lose the inside electrical overhead lights, cig lighters and trunk light. Then, as strangely as they went out, they come back on. But it's a real pain when they go out..no lights at night, no power in the outlets and no trunk light....ARGH........any clues out there???

Replying to: avidus (Aug 20, 2007 4:15 am) Has someone put an after market radio on the car? Has someone put an after market alarm system on the car? Has someone put a remote start system on the car? Any of these has a high possibility of messing up the electronics on a Cadillac, or any other vehicle. |

Replying to: medic2586 (Sep 09, 2007 11:03 am) They replaced, per receipt, a relay, a module, etc in the attempts. I think the final fix was a short or bad connector, not a separate piece of hardware. I didn't ask much about it, just kept taking it back. And on the last trip home, after 30 minutes on my driveway, I saw green fluid. Took it right back and got a replacement water pump in less than 2 hours. Had it in stock, knew what the problem was, quick replacement - this makes me think lots of them leak. And, you have to disconnect the battery to stop the interior lights, until they are fixed.
