help! no dash lights

[need psi]

hey guys on the way home last night i done a huge compression lock up and the entire car bounced around and shook everything. the car is an ea fairmont ghia. the dash all works including speedo but no interior lights work except for the speedo back light. so at night i cant see my tacho or temp guage but can see the speedo. would i have just blown a fuse or shook the earth point or something else? is there an earth point for all that? any help on what it would be is appreciated.

Ehab
