turn signals not working by davidgolfer

I have a 1999 Deville and the turn signals stopped working. When you turn the left on it is just stuck. Same with the right turn signal. I checked the bulbs and replace to fuses. I bought a flash fuze from the dealer,but can't find where to plug it into. Anyone have this problem or know how to fix this. My other cars, I just replace the light bulbs and flasher and this fixes it most of the time. Please help.

I just bought a well taken care of 99 Eldorado last Friday and as of Saturday it started doing this! The starter makes a strange clicking noise, the battery shows like 10 volts, then the clock and onboard diagnostics reset themselves (but strangely my saved radio stations are "remembered") and sometimes the trunk and fuel door will pop open. I replaced the obviously stock battery on Saturday with some Bosch upgrade, and it ran fine for 3 days. Today, it started doing this again! The guys at work jump started my car and I drove it home and it was running fine, with a battery voltage of about 13.0-13.5. Once I got home and turned off the car, it wouldn't start again, and the voltage dropped to like 9.5 then 8.5 until I gave up. I jump started the car again and drove it to Pep Boys and had the alternator, starter and battery tested and they are fine but they said the NEW battery, which is less than 3 days old, has a bad cell. I don't know what the chances of this happening are, or if something wrong with the car destroyed the new battery, but I'm hoping (praying) this third battery will work! Did you ever figure out what the deal was with your Cad? I see you posted this in May, so maybe the problem has been diagnosed by now, I'm just trying to save myself a bunch of hassle and headache of having a dealership or mechanic guinea pig it to try and determine what the problem is. Any info you can provide is greatly appreciated!

After sending the alternator out to an expert, it was determined it had to be replaced. An internal part had burned out. As they are water-cooled, the total cost was $1050 CDN. The alternator is in an extremely difficult position to reach and my mechanic of 25 years charged me almost no labour. I hope this is not the case with your unit.

Well, if the battery has a bad cell, it needs replaced, new or not.
 
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.

1986 Cad Deville by sassy13

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????

Interior Lighting Goes Out and no trunk light by avidus

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???

If your car has battery run down protection, it might be turning them off to save the battery. I've had my trunk light do this when the trunk was open for a long time. Then it comes back on a little later. 2005 Deville.

No, I wish it was that simple. The lights will go out for months at a time and wont come back on at all, except bu surprise, the whole thing works great, so nobody can figure it out. It must be a short somewhere but dont know where.If I plug in a jumper box into the cigarette lighter, then the lights work, so they must all be on the same circuit and not getting power from the car battery. But I have checked the fuses and they are all fine. So I just dont know...
