2002 Nissan Maxima with 118K miles. Heating and A/C buttons that turn the fan on differnet levels doesn’t work. It will cut on/off but the setting can be on low and it always blows on high. The temp. is correct(heat or cold) on what we set…it just always blows on high no matter what we set. It is a bush button kind of setting not a dial that you turn. Any ideas?
Take heart, this is likely not a difficult nor expensive repair. You most likely have a burnt out blower motor resistor. You can probably change it yourself if you can locate it. I don’t know the Maxima. Sometimes these resistors are behind the dash and other times they are in the engine compartment. Check a repair manual.
