Strange electrical problem


Recommended Posts

So when my headlights and fog lamps are turned off my left side light turns on. You know,...the one that sort of wraps around the side of the car. There is a clear part of the lamp and a amber part and only the clear part is lit. Anyway when I turn on the fog lamps the wrap around light on the right side wont light up. I dont think the bulbs are burnt out because when I turn on the right blinker it seems to work. I dont know if you guys follow me but in a nutsheel what im saying is that the clear bulb on the left side is always lit even when the lights are off and the same bulb on the opposite side wont lite. Help.

How about the turn signal switch inside the steering column. If the side bulb eventually blows altogether then I would be real suspicious about the turn signal switch.

Ok so I noticed that the light that is on on the left is the light that illuminates the side while turning. Its always on now. Also...MY STEERING WHEEL HAS BEEN SMOKING....perhaps related? Maybe maybe?

I am going out on a limb here, but I am going to say YEAH!

That looks tipical for bad grounds. Plus, possible short between two cuircuts.

I reccomend to check grounds at first. Turn on light, then measure voltage of a ground. It should be zero and it should not change when you turn on/off.

Smoking steering column indicates the turn signal switch. Right before I had to replace my turn signal switch white wisps of smoke would come from the steering column. In my case the left side light wouldn’t light at all. After replacing the switch everything was back to normal.

If you try to replace the turn signal switch, read ALL of the instructions on deactivating the air bags. Those things can kill you if you are close enough to it & set it off! :(:(

If you are not comfortable messing with explosives (sodium azide & a detonator) then I would suggest that you find a reputable shop to do this type of repair.

You can still save some money by buying the switch from Brasington or GM Parts.

it is so true about those air-bags. I'v seen the after effects on friends who have had the air bags go off. There was a busted thumb, road rash burns on wrists and a friend of a friend that did not have the seat belt on and had a badly brused face. So if your going to play with the steering wheel ( be Aware ) and be safe..

I bought the switch from a Cadillac dealer for $45.21, which was less expensive than the inferior Napa switch. The part No. for you switch is ACDelco Part No. D6241A. You can confirm the part number at:

Here is a post showing the defective Napa part:

Im actually more comfortable with my hands on explsoves than under the hood of a cadillac. :P We had a kid where I go to school hook up his newsensors and re fuse his system BEFORE putting the airbag in, he did that last, and long story short broken nose. Anyone have the procedure for this,...replacing the switch that is,..not breaking your nose. I already know how to do that.

The turn signal switch replacement is rather involved...

Here is a pic of one we did recently....'97 caddy...
