Flickering lights on 2000 Montana

Lights pulse when vehicle is running. I believe it to be a ground problem but don't know where to start.

    I also experience the same problem. ALL lights pulse, including the headlights, it is VERY noticable and happens at all speeds.

    Mine is more prominent at idle or low speed. I had been informed it is caused by a defective alternator which sends a false message to the battery and charging system, this has not been confirmed though.

    My interior lights and headlights also pulse, but are most noticeable at slow speeds.

    I had the same problem when all lights in and outside of my van were flickering. It became so bad that at night if i was following cars they would pull over. Come to find out that is was my altenator. It was over charging. we put in a smaller one and it works fine now

I had the same problem with my van, after taking it to the dealer they said it was not the alternator and could not explain the problem of the flickering. I'm not an electrical genius, but after i done some research of my own i learned it could be the diodes inside of the alternator. At this point I had 2 options, rebuild the alternator I had (with a one year warranty) or buy a remanufactured one (with a life time warranty). I chose to buy a remanufactured alternator and have had no problems with the flickering. Note: carfully inspect remanufactored alternator before leaving part store. I did not inspect part until pulling it out of box after 2 hours of knuckle busting labor to find out that new part had a busted housing.

I have been told there is a ground wire under the hood that is used for the dash lights and has a problem about coming loose or corroded. Hope this helps.

ok, i will try and help you as much as i can. first you should be getting 12 volts a pulse and a ground( negative ). if you're getting the 12 volts and the grounds but no pulse the the car has 2 sensors, one is the cam and the other is the crank. those sensors provide pulse to one for the injectors and the crank is for the coil packs. you can test for pulse by using a noid light or the normal test light. just connect the test light to 12 volts terminal and have someone crank over the engine. if you don't get a low flickering light then you neeed to change the sensor

My parents had the same problem with the dash lights on there Montana. After 7 trips into the shop we determined ourselves that there is a wiring harness that runs under the carpet on the drivers side in about the location where most people rest their left foot when driving. What was happening is the wires had worn through the insulated cover and was grounding out on the bare floor under the carpet. We were able to tape the wires and wrap them with hockey stick tape to prevent it from happening again. It is worth looking into.

did the battery check to be good? are the connections on the battery tight and clean? if so you may be getting a bad body control module , it controls power and ground to the systems you are having problems with.also check the ignition switch to see if you are getting power out of it to power the vehicle up.

I have a 2000 pontiac montana and the lights are not working righ


If you live in a area in which salt is used on the roads, you probably have a corroded ground connection. These can be tough to find since there are several grounding points in most vehicles. When a ground fails, the current (the applied 12V) will find its own path to ground and can pass through different light bulbs on the way. If it was only the signal flasher creating problems, this can be caused by a single failed light bulb; the flashers are thermal devices and when the current is lower than it should be, the rapid flashing alerts you to the failure.
You might consider buying an after-market service manual from Haynes (my first choice) or Chilton. The manuals I have for our various vehicles give a general location for the grounding points; for example, 'Right side engine'

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.
