Okay, I really appreciate if you all can answer my problem.

I got a LED bulbs for the all 4 doors. Installed em but something's wrong.

When all doors are shutt in, the lights came on... when the doors are open, the lights goes off...

HELP! I read something about not grounded???/

 

Sounds like they might be reversed in polarity... anyone else care to chime in.

 

Here's another thing.. I tried to put back all halogen bulbs back in, they do no longer lit up but I tested on other car, it wroks?

 

How do I fix it?

 

I installed LED for the dome light and it work perfectly. Where did you get the LED from? You might want to flip the LED from left to right or right to left. Make sure you flip the switch off before remove or installing the LED.

 

As for the dorm light, on the front end, it used wedge type, back end use bulb....

so... on the auto swtich, it stays on no matter what.. even tho the doors r closed, ill check it soon
