i bought a blue led for my courtesy lights, and it didnt light up when i put it in. And now all my interior lights wont work, domelight etc and also my kelyess fob wont lock or unlock my car. is this a blown fuse or somthin, and wat led should i get since i bought the wrong one im guessing?

 

LED's are diodes. In other words the only work in one direction. Flip the LED and try it again. You may have blown a fuse when installing the LED initially. Check your fuses in the drivers side kick panel. I'm not sure which one it may be but look on the inside of the fuse panel door for a list of fuses and what they are for. Hope this helps.
