On my 2001 Buick Regal LS/R my odometer and gear selection on my dash don't lite up. Also my fuel guage doesn't work properly as if low on gas it will climb as I accelerate and goes from just under a half of tank to the near empty with the low fuel lite going on and the car is near empty. Finally my door power lock control located on the door just works for unlocking and not for locking. Are these all connected some how as they seemed to stop working at the same time
