1999 Maxima GLE, 85,000miles
Recently replaced (2) O2 sensors because "check engine soon" light went on, computer said codes 135 and 155.
Check engine soon light went out and then came on again. Now i sometimes lose all power to instrument panel, power windows ac switch and radio. Car runs fine and headlights stay on. When lites come on again so does "check engine soon". Have replaced sensors, battery (broken post) and ignition switch. Also replaced some fuses even though they weren't blown. Help, am afraid engine will die when I am on the road

Everyone-it ended a bad relay located next to fusebox.

I know you said you replaced some fuses but I had the same problem and ended up replacing the 100a main battery fuse it didnt look blown but was. Maybe yours is just lose causing the temperary outages it has screws that hold it in place.

Now get no power at all to instruments, power windows radio turn signal. Found the 120 amp fuse-it looks ok-can't figure how to get it out. Other fuses in that panel pull out, 120 amp won't come out. This is a 1999 Maxima GLE.

Pulled 125 amp link and 65 amp link both tested ok. Started car and everything went on???? Starting to think after market O2 sensors we had installed might be affecting computer and "check engine soon" light still on.
Going to try putting in Bosch sensors that has correct color wires. Thanx anyway!
