I was changing the light bulb in the trunk, with an LED, when something happened. The LED came on briefly and then went off. I put the original bulb back in but that didn't work either. I thought that maybe the battery died because the car had been sitting for a few days. None of the interior lights came on when I opened the driver's door but the dash lights were fine and the car started. I also noticed that the keyfob isn't working either. Is it all related to a single fuse and which one is it?

 

I think I have found the answer to my problem.

Fuse #6 (7.5A):

• Courtesy Lights
• HandsfreeLink Control Unit
• Ignition Key Light
• Keyless Receiver Unit
• Map Lights
• Power Mirror Control Unit
• Power Seat Control Unit
• Roof Console
• Trunk Light
• Vanity Mirror Lights

 

 

LEDs and the interior of the 3rd gen TL do not mix well. I strongly suggest not using them in the dashboard anywhere. The interior circuits are balanced regarding resistance. And any alteration may not only pop a fuse but also the entire panel. I forgot what they call that thing
