70 Chevelle Malibu Convertible: When I shift into park, reverse etc... the needle doesn't move. Whats involved in fixing this? What are the most common causes for this?
Do I have to pull the entire dash out?

Any help would be appreciated.

Its an EZ fix. Look under your steering column there is a screw that comes loose . Holds the wire that is the indicator.

Frequently this wire either comes loose or breaks. Should be pretty simple.
