1995 Pontiac Grand Am Dash and rear lights

I just bought this car from my buddy it runs great no real problems except for the dash and rear lights wont come on by dash lights I mean the lights behind the fuel and speedometer and the temp gauge. They wont come on the tail lights will not come on either, I have no clue about cars my buddy was looking it over and all the fuses are fine his dad looked at it and he said he would have to look at it when he has room at his shop, I just want to cut the search down any help would be greatly appreciated.
