Head lights and dash lights flicker while driving at night.

At night while driving my dash lights and head lights flicker continously for awhile and then they quit and suddenly start flickering again.They go very dim then bright while excelerating and at a continous speed.i replaced the alternator a year ago and the battery 2 months ago.I also replaced the belt and belt tensioner 2 months ago.i have taken it to advance auto and had a voltage test done on the battery and alternator and everything is working properly.Any suggestions on what else it could be?

well to make sure it is the laternator start the car and pull the positive battery cable. if the car dies it is the alternator. and usually even on the new cars. it is easy to get to. just look at the front of the hood for the belt diagram and it will tell you how to release the belt.

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: Alternator keeps going bad - three so far. Battery light flickering off/on now.

Having worked for an Isuzu dealer I have seen this a lot with aftermarket alternators from places like auto-zone, napa etc. For some reason they will do strange things in these vehicles. The fix was to get a Isuzu alternator. We did have good luck with Beck Arnly alternators also. We also had a local rebuilder repair some with good luck too. If all else fails get a used one.

SOURCE: flickering lights

In some 1999/2000 Cougars the wire between the battery and the voltage regulator(altenator) had a resistance reading that is too high. Ford has issued an TSB 00-25-6 that has instructions on how to replace this wire. The part # for the replacement wire is
1S8Z-14A411-AA. I'm in Michigan and a local dealer found one for me in South Bend,IN

Head lights flicker at night every once in a while.more and more recently. a couple of times every mile. all other dash and radio lights seamed fine. have not had any issues with day driving or starting.


Sounds like a ground issue to me. I would have the wiring checked for any ground issues. If its getting bad this could cause the flickering as you drive. This is what I ran into a while back. Hope this helps!!
