So I was changing my interior bulbs to leds when I ran into a strange problem that I cannot find the answer to.


This happens with the drivers side rear door. I open the door and the coat hanger light and door light are on but extremely dim. These are fresh LEDS but I figured the leds could be faulty so i swap them, same thing. I press the coat hanger button to turn it on and boom that light is bright as hell but the door light is still dim. I open the passenger side and both are bright. Does anyone know what is causing this or what the issue may be?

Upon installing these I noticed that neither of these lights even came on when i opened the door! mind you this is a 1998 gs400 with 54k miles on it. Help?!?!

 

Try and take a small flat blade screwdriver and move the contacts closer to each other then put the led in.

 

Will do but i dont think that will do to much since when you push the button the coat hanger light is perfectly fine. Thanks for the tip

 

I moved them a bit closer and they actually wouldnt turn on, I then spread them apart a bit further and they are still dim. Not sure wtf is going on but It must be something with the car, rather the bulbs since I swapped bulbs with ones that work.

 

When you open that door, does the orange door open light on the dash come on?

 

Interesting you say that because I dont believe it does. This door has always seemed to be giving me a problem, Ill come out to it to see its slightly open. Last night I was in the back seat with both rear doors open, i shut the passenger side door and the dome light shut off, when it should be on.

I think your on to something, Ill check at lunch time!

 

Same thing happened to me. I never fixed it since it doesn't bother me.

Yeah OP, I had a similar if not identical problem to Thomas. Check the following link to see if you problem sounds like mine as well. It's funny because my rear, driver-side puddle light is the same one I had problems with too. But, like Thomas, it doesn't really bother me all that much so I never bothered fixing it.

Yes the dor adjar light does not come on when I open the door, neither does the dome light. Has to be the door module, Ill try and find a cheap used one and replace it. Thanks guys!

 

it doesnt HAVE to be the door ecu (which is what i assume you mean by the module), it could easily be the door switch also

 

hmmmmm how do i go about testing either one? when it comes to modules and ecus, I just replace what I think is bad and hope for the best lol

Heres what happens when i open the door.

The door puddle and coat hanger lights do come on but very dim, the door ajar light does not come on and the dome light also does not come on.

 

If you have a voltmeter you can check the current passing through to those outlets. If you have a poor current running to the light outlets then you can say with confidence that it's the switch. If you don't have a voltmeter I would just bring it to someone who is good with car electronics and they can probably narrow this down for you.
