I replaced all the interior bulbs for LEDs mostly to reduce the battery consumption as I keep the doors and liftgate open a lot as I haul a lots of stuff for my tennis program and need to load and unload daily.

After the istall, I noticed the rear footwells are no longer lid up as well as all three lights on the tailgate (one red and two white lights).

I thought maybe I burned a fuse, I looked into the manual, I couldn't fine a fuse assigned to those lights. All my other interior lights are working fine.

Any help or suggestions would be greatly approtiated.

Thank you.

Anyone ^^^^

 

I changed my interiors to led as well. Mine is a 06 CTTS I don't know if there is a difference but it could be 1 of 2 things. 1 check those lights to make sure they fit perfectly because my footwells and tailgate lights keep going out bc the bulb was slightly loose and I had to bend the housings slightly to make them stop turning off due to any vibration, hitting a bump, closing the tailgate, ect. The second thing is it may not be the fuse annotated in the manual. I shorted my glovebox light and the front footwells, glovebox and overhead lights turned off. I had to check every fuse in the manual and found the fuse after pulling all of them in the fuse box on the drivers side dash it was labeled something that I figured had nothing related to lights in the manual but I just went one by one until I found a fuse that was burnt out. It's a PITA but it's what worked for me. Hope this helps and good luck

 

Thank you, TurboSman!!
I went through all the fuses and #19 was burned out. It fixed the lights on the back of the tailgate. Awesome!!!

As far as the rear seats footwells - no progress.
I checked and tested the bulbs and they are fine.
I remember that the rear footwells were already out before I got to them to switch the bulbs to LEDs. I did them last. I thought maybe they were related to the tailgate, but apparently not. They were working just fine before I started to switch all the other bulbs. It's not a big deal to me as no one rides in the back regularly. But I am sort of a guy who likes everything to work. Any suggestions are greatly appreciated.

 

Did you try flipping the bulb 180 degrees. It might be a polarity issue

 

Yes, I did.
I plugged the whole unit into the door location. It lit up just fine.

 

Drove the car at night for the first time since the swap.
The LEDs in the front footwells are now blinking when the car is in motion.
The light is on for three seconds then goes out then lights up again. It's not due a loose bulb as both footwells blinking simultaneously and the blinking is in a steady pattern. Anyone experienced that after swapping to LEDs?

No issues when car is parked as the LEDs are fully eliminated. It's only when you drive as the power input is reduced.

 

It's a resistance problem. My LEDs blink when I start the car. It's a sensitivity thing. It may also be something else related to the connection.
