So the other day i took apart my cluster gauges to change the lights to red LEDs. I wasnt too sure on how to remove the original lights in them so i took them to a shop and the guy took off the black thing that is basically where the needle for the speedometer goes. After realizing that we didnt need to take that off we put it back on and i finished putting the LEDs on. Now the speedometer needle won't move at all. Anybody have any idea how to fix it?
