Hello club lexus

I hope someone could assist me with solving my light problem!

The car is a 1993 LS.

The problem is that the Position light stays on after shutting the engine and leaving the car. Doesn't matter if I try to turn on/off the light switch arm or lock, unlock the car. They only way I can shut it of is by taken the negative battery pole off! Has anyone experienced this before?
I'm not sure that its called position light in english but here's a pic that shows the lights I'm speaking of (marked with red)

 

Further more.. I've just pulled all fuses and relays for the lights. But nothing changes, they still light up !!!

 

Is it connected to an aftermarket alarm system?

 

does your interior dome light stay on too? sounds like a door sensor died.

 

Hi guys

Thanks for the feedback

I just found the problem. It was the taillight relay! A bit tricky to get to, because its mounted above the fusebox in the cabin.

 

How did you get to it?
