I just replace all of the bulbs in my steering wheel controls not hard at all and looks great. i replace them with 3mm blue less and very inexpensive. i do have a question though, after i replaced them i plugged them all in and when i plugged in the last one they all went out. is there a fuse somewhere i cant find to check? i have already checked all the bulbs again they all work fine out of the truck.
