Brake light relay

Post by [email protected] »

I have a 2005 xc90 2.5 the rear brake lights are not working properly the top LED works fine but the two lower lights do not. I see that 2003 models have a blue relay in the left rear fuse panel but this one does not have any relays on that panel... Is there a brake light relay on this cars. if so where it it. can anyone help me find the problem with the lights. I call the dealer and even the dealer cannot locate it on their computers.. thanks anything will help.. Dan

There is no serviceable relay 2005 and later.
The system will shut down the transistor circuit if there is a short.
