Hi I just got a 1990 pathfinder xe for $750 the car is good shape but there is something bothering me the only lights in the interior that work are all the cluster, the A/C controls but not the on/off switch and the shifter console but everything else like the switches in general (not shure if the power window switches are supposed to light up too) dont light up, also only low beams work no high beams, please help me is complete darkness in there I cant locate the switches the dimmer is all the way up, radio works fine aftermarket sony, dome light dont work, rear dome light works, thanks.

Check for any blown fuses in the cabin fuse box. Check the dome light bulb, it's probably burnt out.
Goodluck
