hello guys,
trunk light on my 05 TL turns off when i open the trunk lid all the way and might come back on its own. The light also flickers if i swing the trunk lid. anybody knows the problem is? Thanks

 

Do you have an aftermarket light/LED in there? If so, it's probably going out or it's not secure in it's socket.

If it's an OE bulb (or OE style bulb), it's probably not secure in it's socket or it's going bad.

 

It's the original bulb, I will check the bulb first. Thanks

 

just find out that the flickering trunk light triggers the car alarm. can a bad bulb cause that?

 

checked the bulb and fuse, they are good. there is no voltage when the light is off according to a volt meter. any body has the same problem? thanks

 

Switch the bulb with one of the interior bulbs and see if it still does it. I think they're different wattage but it should work.

My guess, the connector.

 

same thing, its the power got cut off when i swing the trunk lid or shake the cable that attached to the driver side trunk hinge.
Thanks

 

check ur trunk switch....it is the switch which tells "trunk is open" hence the light comes on.....

if ur bulb is properly in the slot like it should be then i would blame it on the trunk switch....

 

Are you talking the trunk release push button under the dashboard?

 

^^^ no the one in the trunk....lemme try to get a pic of it tomorrow....

its like your door switch, basically tells if your trunk is open or close....another way to check if the switch is going bad is:

if your inside your car, does the "trunk open" indicator go on randomly ?

 

Thanks!
no, "trunk open" indicator is normal.
does your trunk release push button light up? mine doesn't

 

^^^ no it doesnt light up, but when your trunk is open is does display in the MID....

damn so the MID is fine so am guessing the switch is working fine
do the lights flicker when your trunk is open or close ?

 

the light flicker when the trunk is open, especially if i swing the trunk lid up and down. i am guessing is the bad wires, but i don't think the trunk light wire is attached the trunk lid thou. what do you think?

 

^^^ correct the wire is not attached to the lid, but they are all "zip-tied" at some point

darn it, i did try everything cudnt troubleshoot this one

 

Thanks Swoosh. i will try to find the wires when the weather gets better.

 

^^^ not a problem dude....

but yeah, if you get in ur trunk and start taking the insulation/carpet off, you will find the issue
