Question about Cars & Trucks

1 Answer

Headlights/fog lights/courtesy lights/interior lights flickering

For about a year have seen this problem. Started off very minor but has gotten quite bad now, especially at colder temperatures - often seems to disappear after truck has been running for a good 15 minutes or so. Battery recently replaced, have talked to the mechanic a few times about this and they have checked routine things - alternator, huge 175 amp fuse at rear of vehicle...several friends have suggested a relay but there are several relays controlling different lights according to owner's manual so not sure they'd all go at same time...ideas?

    Thanks Stephen, I've heard these things suggested before - I'll check the grounds but how would I hear a relay clicking? Is it pretty noticeable, and would it click at the same frequency as the flickering? Thanks

BAD GROUNDS. check all the negative grounds and make sure they are all good also check to see if you can hear any of the relays clicking , usually indicates bad relay or a bod connection to the relay

SOURCE: Flickering Lights

You do need an alternator. Nissan has a campaign on Maxima alternator in certain years such as 96-98 I believe. Go to your friendly Nissan dealer abd have them punch your VIN number into the NNA net. they will know and that will tell them if your vehicle applies by the VIN. I have seen the alternator on fire. There was fire inside of the alternator. Have it checked or the car can catch on fire.

SOURCE: Both fuel pump relays run

You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!

Half of electrics stopped working but yet the fuses are okay


Time to do a wiggle test of the fuse box wiring. The circuits mentioned are not directly connected , but may travel through common wiring plugs. Try the fuse box fuses again (there may be more than 1 fusebox) Interior light / Radio / Antenna / Clock may be on a battery circuit but not connected to the Fog light not the turn signals other than a connecctor plug or simular.

Fog lights will not turn off on 2002 Jeep Wrangle Sahara


Or you could just pull out the relay under the hood, it's marked fog lights, pull the relay out. If your hi beam indicator is flashing with your fog lights on them selves. Could be the multi function switch. That controls turn signals, headlights, fog, I have seen many of those go bad.

Electrical problem


I just had the same issues. No headlights, interior lights, power door locks, radio controls on steering wheel, or dash lights. Pulled every fuse in cab and under hood, not a one was bad. I disconnected the battery terminals for a few minutes. When I reconnected them every thing was working.
