trunk light/front side marker not working

[theyaris123]

Hi, I'm using Yaris 2007 LB base.
I try to change my trunk light with Phillips C5W LED bulb, but then its not working. I try to search already but cannot find answer that i need. ( the old bulb inside is look fine too, not disconnected as other bad bulb, so its might not be the bulb )

At first i thought it's the fuse but i read from some tread that trunk light is using the same fuse as dome light. My dome light is working fine. so if it's not the fuse what could be the problem here?

Could it be the Latch trunk switch? ( i got that idea from some tread also ). if so how can i fix it?


Another question is i also need to change left parking light and right front side marker light, should i do that by myself or should i have the dealer do it ( i don't want to ).

I try to search this forum and google for the answer, but i can't seem to get the answer i need. so any answer is appreciate. Thanks you in advance.
