my 2000 max has been making some weird noises and i was wondering if anyone knows if this is normal or if you have any idea what could be wrong with it. (i have the auto climate control) when the heat turns on the fan behind the radiator also turns on. i woudlnt have thought it was strange but the noise is really loud. i didnt notice it until one morning i started up my car and i could actually hear the the noise from the car from the fan inside my house. it does it on a cold start and even when its warm. i have a few friends with maximas and none of theirs does it. if u have experienced this or could give me a little insight to what the problem could be id appreciate it, thanks

 

sorry dude no clue.

 

are you sure its not one of the belts? ive been having a strange high pitched noise at startup but after investigating its actually the power steering belt. cars at 62k so im having belts replaced tomorrow ~

 

Does it do it when your climate control is in ECONOMY mode vice AUTO? If not, it's probably just the A/C kicking in. Unless you're in ECONOMY mode, the A/C will run even when the heater is on in order to provide you with dehumidified heat. If I remember correctly, the fan runs at idle in order to force air thru the evaporator.

 

Yeah, although it actually blows air through the condenser (evaporator is in the dashboard, next to the heater core)

 

Ooops... Yup, you're right..

 

yeah, its definatly not one of the belts, theres no high pitched noises or anything. all it is is a really loud blowing noise from the fan in the engine bay. im wondering why the fan turns on when ever the climate control is on. it does it on all modes (auto, manual, econ, and even defrost) so i dont know.
