Question
I have a 1999 Maxima GLE Recently had o2 sensors changed after market brand. Since then lose intrument lighting,radio, ac switch, signal indicator, radio. Cars runs and headlights ok.
I put new battery in (its good) and a new ignition switch. Checked fuses and cleaned a lot of contacts. Friend suggested I change 120 amp battery switch, even though it looks ok! ( haven't done it yet-other fuses in that box pull out-can't figure how to get the 120 amp one out-won't pull out)not sure that is answer anyway. Help

Answer
Check all fuses and relays.The 120 amp will come out ,it may be tight but it does come out.You can tell if its blown without removal.You will need to back track and see where the fault is.The radio,turn signals etc have their own fuse and the dash lights may be included with another component so look at all the electrical items and see.Was the battery put in the wrong way by chance?If so even for a few seconds it will blow a lot of fuses and the main 120amp ignition but usually if it is blown the car wont start.I would check the fuses by removing 1 at a time all of them.Under hood and dash.
