SRS Light - always on
ABS Light - intermittently on and off
E-Brake Light - just started staying on

The E-Brake light was randomly coming on and off as I was driving this morning and decided to stay on the whole ride home from work. The ABS light comes on randomly as I drive then goes off...which leads me to wonder about the random noise I hear from the front right of my car when driving. The SRS light is most likely due to whoever swapped the interior as the had to take of the steering wheel (from what I have read)

My question is...how in gods name do I fix these issues?
