im taking the ride in to a friends shop on sat but till then i was wondering if anyone has experenced this. my cluster dims slightly (not dramatically but noticeably) when i either have my heater on or play with my driver side window switch. if im driving the lights brighten up but at a stop thats when its noticeable. if my headlights are against another car or wall i notice they slightly dim when i play with the switch. now if i play with the switches for my other 3 passenger windows through my driver side nothing happen. alternator was replaced less than a year ago and is still under warranty. i have to change my belts cause they whistling at times, 80% of the time is when the heater is on. any advice would help even though we'll figure it out this weekend, its still bothers me now.

 

change the belt

 

It happens in most cars including the Maxima.. try not to pay attention to it

 

just in case someone post "use the search" i did... i pulled 20+ possible causes but noone ever replied with an update reporting they did a certain fix and problem was solved.

 

Had the same problems for a month. Pretty sure it's the serpentine belt. Get it changed ASAP.

Edit: Forgot to add, have them replace with the Bando belt. DON'T use Dayco or whatever it's called. Had to change the belts twice because Dayco belts suck. Bando belt worked great though.

 

my friend is a tech at a infiniti dealer so the belts he was goin to replace this weekend where nissan brand. i only thought about changing my alternator and ac belts along with a rear frozen caliper which was the main reason for the visit.

 

Belts. Also look into a grounding kit, and doing the Big Three.

 

grounding kit....
i did search for a grounding kit actually, hurt my head! i looked to purchase online and diff vendors had them in 8g while the info for the most part i got from my search on here recommened under 4g. i emailed a member who actually sold them before to see if he still does.

 

Belt + Grounding Kit... If nothing else, get LEDS!

 

yeah i experienced that same problem, i'm about to look into it and change the belts and possibly a new gournding kit
