Help...LEDs not working

[450]

Ok I have been installing my LEDs for my interior lights and at the moment have gotten stalled on the window switch and door lock switch light. I started on the passenger side and got it hooked up and it worked all day than this evening I started on the driver side and got everything soldered and worked fine, well I re-soldered the driver side light so it would fit correctly inside of the light channel and now neither of the lights work on the driver or passenger side. It kinda seems like I blew a fuse and I looked at a few of the fuses but I am not sure if they were the correct fuses but they were all fine. Also the switches still function the doors lock and the windows roll down the switch just doesn't light up. I am assuming it is something stupid but if anyone has some insight on this please feel free to chime in.

get a volt meter and start testing.

If I get one where would I be testing at? I know obviously on the circuit board where I soldered in the LEDs but where else would I check if that's not where the problem is?

When you re-soldered, did you remove the LED? LED's only work in one direction, and if you put it in backwards, it won't do squat.

Yeah I made sure I didn't but I flipped it around just to see and it made no difference. The thing is that the passenger side was working and was all put together but after I got the driver side going both stopped...
