cheap-ass

I have a few electrical problems that i would like to fix just for convenience the first is my dash lights dont work such as my high beam, low fuel, 4x4, and any others that i might not know of but my e-brake, and seatbelt do work also my dome lights and door buzzer work about once or twice a month. This is all in my 1990 pickup extra cab with power windows if that helps any with the door buzzer and dome light i would just really like to have all these working for more reassurance.
