i just replaced my gauge lights so they would be blue. i got the bulbs from autozone. they came out fine and the new ones went in fine. but ive tried everything and they aint working. any ideas?

 

AUTOZONE, NOT GM.....hummmmm, i wonder why it isn't working properly, why dont you swap the old bulbs back (the O.E ones) and see if they work

 

could be a polarity issue try rotating the bulb 180 degrees....when I first put my domes n maplights in some worked n some didn't it was the polarity......also I hope you didn't buy the painted bulbs from autozone if so they'll prolly be white again in a matter of weeks.....

 

^ I had the same issues with polarity. I also had a minor problem with the terminal connections. Make sure the connection points in the socket are touching the bulb.
Autozone eh? You know you could have gone to ebay and gotten blue LEDs for about $5 for the whole set. Hell, I bought ones for ALL my interior lights for under $20.
